Masayoshi Iimori: Biography, Discography and More | EDM Encyclopedia
Introduction
Masayoshi Iimori is a Japanese electronic music producer and DJ whose career spans from 2015 to the present. Based in Japan, Iimori has developed a catalog rooted in trap, grime, and bass music. His releases have come through labels within the Monstercat ecosystem, including Silk Music prior to its acquisition by Monstercat in 2021, connecting his work to an international audience beyond Japan’s domestic electronic music scene.
Iimori’s entry into released music came in 2015 with a pair of EPs that established his production voice within competitive trap and bass circles. From that starting point, he built a discography that includes two albums and five EPs over an eight-year period. His output reflects a producer who works across multiple tempos and energy levels, from aggressive club tracks to more melodic bass compositions.
The Monstercat affiliation placed Iimori within a label network known for supporting electronic artists across house, trance, drum and bass, and bass music subgenres. This positioning gave his releases distribution through major digital platforms and exposure to listeners the label’s curated playlists and compilation series. His catalog, ranging from debut EPs in 2015 to a retrospective collection in 2023, documents an artist working through the possibilities of bass-driven electronic music while maintaining a consistent presence in the trap and grime space.
Iimori’s production timeline is marked by clear phases: an introductory period in 2015 with dual EP releases, a middle period from 2017 through 2019 that expanded his sound with new EP projects and a remix package, and a later phase beginning in 2020 that introduced full-length album releases. Each phase added layers to his technical approach while keeping the bass-heavy foundation that defines his work.
Operating from Japan, Iimori represents a segment of the country’s electronic music producers who have found audiences through international label partnerships rather than relying solely on domestic channels. His presence on Monstercat’s roster connects him to a global distribution network that has supported electronic music releases across streaming platforms, digital stores, and label-curated compilations since his first appearance in 2015.
Genre and Style
Iimori’s production style centers on trap and bass music with significant grime influences. His tracks are built around sharp hi-hat patterns, sub-heavy 808 bass, and rapid rhythmic shifts that alternate between half-time grooves and double-time percussion fills. The emphasis is on density and impact rather than minimalism or atmospheric space.
The trap Sound
His arrangements favor quick transitions into drops, bypassing extended buildups in favor of immediate energy. This approach creates tracks suited for DJ sets in high-intensity environments, where momentum matters more than gradual development. Vocal elements, when present, tend to be clipped and chopped rather than sustained, functioning as rhythmic accents embedded within the percussion framework.
Across his discography, Iimori’s sound design has evolved from raw, club-focused productions toward more structured compositions. His early work leans into aggressive synth work and faster tempos aligned with grime conventions, while later releases introduce brighter melodic content and more varied arrangement structures. The low-frequency foundation remains consistent throughout, with distorted bass textures and crisp percussion processing serving as anchor points across different release periods.
The inclusion of remix packages in his catalog demonstrates an openness to reinterpretation, allowing other producers to reconstruct his source material through different stylistic lenses. His full-length releases show an ability to sequence tracks for a listening experience beyond the dancefloor, balancing high-energy cuts with moments of reduced intensity. Throughout these shifts, the core elements of his production remain identifiable: heavy low end, tight drum programming, and an emphasis on rhythmic complexity over harmonic progression.
Iimori’s approach to bass music avoids relying on genre conventions as a static framework. Instead of template-driven arrangements, his tracks feature tempo changes, layered sound design, and structural variations that keep individual productions distinct from one another. This attention to variation within a defined sonic range has allowed him to produce work that spans multiple phases of trap and bass music’s development in the electronic music landscape.
The balance between aggressive and melodic elements in his productions creates a dynamic range within individual tracks and across full projects. Bass drops hit with distorted weight, while synth leads and processed vocal fragments provide textural contrast. This interplay between heaviness and clarity gives his work a sense of dimension that separates it from productions focused solely on impact.

Discography Highlights
Albums:
DECADE4ALL (2020) represents Iimori’s first full-length album, compiling new productions that reflect his range across trap and bass music styles. The project demonstrates his ability to sequence tracks for a complete listening experience rather than assembling standalone singles into a collection.
Unreleased top EDM songs 2016:2020 (2023) collects previously vaulted material spanning a four-year period. The compilation offers a retrospective view of his evolving production techniques, presenting tracks that existed outside his official EP and album release cycle.
EPs:
Break It EP (2015) marks Iimori’s debut release, introducing his aggressive trap production style to the Monstercat catalog and establishing his presence in the competitive bass music landscape.
Break It EP (Grimecraft Edits) (2015) serves as a companion release featuring reworked versions with grime-influenced EDM production elements, expanding on the source material from his debut through collaborative reinterpretation.
TAP (2017) explores clipped vocal samples and dense bass arrangements, arriving two years after his introductory releases with a refined approach to his established sound.
TAP Remixes (2017) presents a remix package based on the preceding EP, allowing other producers to reconstruct his source material through different stylistic approaches within the same release year.
Euphoria (2019) balances melodic elements with heavy bass design, representing a shift toward brighter sonic territory while retaining the low-frequency foundation central to his work.
With no confirmed singles listed outside these projects, Iimori’s catalog is concentrated within album and EP formats. His release cadence has varied across the eight-year span covered by his discography: two projects in 2015, two in 2017, one in 2019, one in 2020, and one in 2023. This pattern suggests periods of active output alternating with gaps during which unreleased material was accumulating for later compilation.
Famous Tracks
Masayoshi Iimori’s recorded output documents nearly a decade of Japanese trap and bass music production. The Break It EP arrived in 2015, followed that same year by Break It EP (Grimecraft Edits), a companion project that reworked the original material through the lens of another producer. These two releases established the foundation for Iimori’s catalog, introducing a sound rooted in aggressive low-end and rapid rhythmic shifts suited for club environments.
The 2017 release of TAP introduced a new batch of original productions, later expanded through TAP Remixes in the same year. This dual-release approach, presenting both original tracks and subsequent reinterpretations, became a structural element of Iimori’s output. Remix packages extend the functional life of source material by offering alternative versions suited for different contexts within DJ sets: some geared toward peak-time energy, others toward more atmospheric or transitional moments.
Two years later, the Euphoria EP arrived in 2019 as the final short-format release before a shift to longer projects. The 2020 album DECADE4ALL marked a transition to full-length territory, functioning as a cumulative statement that drew on years of refinement in the studio. In 2023, Unreleased Songs 2016:2020 surfaced, making archived studio material from a four-year window available to listeners for the first time. The chronological range of this collection suggests that Iimori maintains a substantial archive of completed work beyond what appears in standard release cycles.
Live Performances
Masayoshi Iimori’s position as a Monstercat-affiliated artist places the producer within a label infrastructure that actively organizes live events and facilitates artist bookings across multiple continents. Monstercat maintains a roster of electronic musicians who perform at club venues and festivals catering to bass music audiences. Iimori’s catalog of trap and bass productions aligns with the label’s area of focus, positioning the artist for inclusion in label-curated showcases and collaborative event opportunities.
Notable Shows
The structure of Iimori’s discography, built around EP-length releases and one full-length album, provides a practical foundation for constructing live DJ sets. Each release contributes individual tracks that can be sequenced, layered, and mixed in real time. Producers working in trap and bass often construct sets by drawing on material spanning multiple release periods, creating continuity between older and newer tracks while maintaining a consistent energy level. Iimori’s catalog, spread across eight years of studio work, offers sufficient range for this approach.
The remix packages present in the catalog point to collaborative relationships with other producers operating in related genre spaces. These connections carry practical implications for live performance: shared event lineups, back-to-back DJ sets, and exposure to audiences assembled by affiliated artists. For Monstercat artists, label-organized events and showcase stages at festivals serve as additional performance avenues that extend reach beyond individual booking efforts, connecting roster members with shared audiences who follow the label’s broader output.
Why They Matter
Masayoshi Iimori occupies a specific position in contemporary electronic music: a Japanese producer working within trap and bass frameworks through an internationally distributed label. This positioning matters because the trap and bass music scenes remain heavily concentrated in North America and Europe, both in terms of artist representation and industry infrastructure. Iimori’s presence on the Monstercat roster introduces a Japanese production perspective into a space where geographic diversity is limited.
Impact on trap
The discography demonstrates a pattern of sustained studio work across an eight-year span, encompassing multiple EP projects and two album-length collections. The release strategy reveals an artist who values both original output and collaborative reinterpretation: some projects exist in dual form, pairing original tracks with remix packages that recontextualize the source material. This approach reflects an understanding of how collaborative output can expand the reach of original productions within DJ culture.
The existence of archival material released years after its creation indicates that the volume of completed work exceeds what appears in standard release cycles. For producers and listeners tracking the globalization of bass music, Iimori’s catalog illustrates how regional production traditions intersect with internationally established genre conventions. The Monstercat association further amplifies this intersection by providing distribution and promotional infrastructure capable of reaching audiences far beyond the Japanese domestic market, contributing to a broader representation of East Asian producers in Western-dominated genre spaces.
The consistency of output, paired with the deliberate archival release, positions Iimori as a producer engaged in long-term creative development rather than short-term trend pursuit. In a genre landscape where artists frequently appear and disappear within brief cycles, an eight-year discography with multiple release formats carries weight as an indicator of sustained commitment to the craft.
