Taku Iwasaki is a Tokyo-born composer and arranger who trained at the National University of Fine Arts and Music in Tokyo (Geidai) before building one of anime's most recognizable scoring careers. He composed the music for Gurren Lagann, the Gainax mecha series whose soundtrack helped define his genre-blending, orchestral-meets-rock sound.
Iwasaki composed the full musical score for Gurren Lagann across both the original television series and its two theatrical compilation films, Childhood's End and The Lights in the Sky are Stars. His music swings between bombastic orchestral action cues and quieter, more emotional passages, mirroring the show's own tonal whiplash between over-the-top mecha spectacle and genuine character drama. The soundtrack is frequently cited as one of the defining scores of 2000s mecha anime.
Beyond Gurren Lagann, Iwasaki built his reputation scoring Rurouni Kenshin in the late 1990s and has gone on to compose for a wide range of anime known for stylistic ambition, including Soul Eater, Katanagatari, and Akame ga Kill. His music regularly mixes orchestral bombast with jazz, opera, and even rap influences, a genre-blending approach that has become something of a signature across his catalog.
