Whokill (stylized as w h o k i l l) is the second full-length release by Merrill Garbus' project Tune-Yards. It was released on 4AD Records on 19 April 2011. The album covers a "formidable range of genres and styles" including acoustic folk, rock, R&B, punk, funk, free jazz and Afro beat. As on her first album, Bird-Brains, Whokill relies on heavily layering looped sounds – notably vocals, drums and ukulele – which multi-instrumentalist/vocalist/composer Garbus uses to create her sound. Unlike the lo-fi Bird-Brains, which was self-recorded on a handheld voice recorder, Whokill was recorded in studio, resulting in a fuller and clearer sound. It was produced by Garbus and engineered by Eli Crews at New, Improved Studios in Oakland, California. Tune-Yards also fleshed out the line-up to reflect the live shows, adding bass player Nate Brenner, who co-wrote some of the album's songs, and using horns on several tracks.
