Flatbush Zombies and The Underachievers have joined forces as Clockwork Indigo, and the Brooklyn rap quintet has released the massive new single "Butterfly Effect" to announce its existence. The Zombies' Architect handled production, and the seven-minute boom-bap excursion is the type of thing you might hear from a RZA-Quentin Tarantino collaboration, with a piercing choral/string sample underpinned by a bed of vinyl crackles.

Clockwork Indigo are heading on the Electric Koolade Experience Tour starting October 17 and wrapping up December 7 in Philly.
