After “Arular” made her a household name for hipsters in 2005, M.I.A. proves she’s more than a one-album fluke thanks to her ambitious, experimental and dangerous sounding sophomore album, “Kala”.

Listening to the rhythmic assaults of “Bird Flu” and “Boyz” should further establish the London-by-way-of-Sri-Lanka singer/rapper/producer as the leader in making dance music for anarchists.

As a summer album, it makes for a great soundtrack to the oppressive heat and humidity.
