The title of Lady Sovereign's new album is no coincidence: On Jigsaw, Britain's feisty female rapper perfectly fits together electroclash, indie rock, hip-hop and other happening sounds. At her best, on this song for example, she is a sum greater than the pieces and parts she ransacks and borrows at will. On "So Human," she sounds like a cross between Mily Cyrus and M.I.A. -- and I mean that in the nicest way possible.
