Merrill Garbus (aka Tune-Yards) slayed the critics with her charming debut album Bird-Brains in 2009, a patchwork creation of loops, Afro-pop and electronica recorded on a Dictaphone.

The follow-up tidies up the rough edges a little, but don't fret that her avant urges have been dampened – whokill is one of the most distinctive-sounding records we've heard this year. Just listen to Powa, for instance, which starts out as a gentle ukulele strum before a detour into cosmic-rock territory that ends up falsetto-ing off into some far-flung sonic galaxy.

Let us know what you think below – the Guardian's Film&Music will review the album this Friday.
