Shakkazombie is a Japanese rap group consisting of three members (MC Osumi, Tsutchie, and MC Hide-Bowie). They formed in 1994 when Tsutchie joined Osumi and Hide-Bowie who were already making music at the time and released their first single "ShakkAttack" in 95. They are credited for introducing many up and coming artists in their collaborations.

Their song 空を取り戻した日 (Sora wo torimodoshita hi) was featured during the credits of Session XX, the mid-series recap episode of the popular Anime television show Cowboy Bebop. The episode was only shown once, so the song was never featured in the "Cowboy Bebop" soundtracks.
