Au Revoir Simone is a female trio from Brooklyn. If anything, their music is pretty indie pop (some songs a little more electro). They formed in 2003 and have released two albums so far.
I'm currently listening to their latest album, The Bird of Music (2007), and loving the song "A Violent Yet Flammable World".
Au Revoir Simone - A Violent Yet Flammable World
The band released a remix album of The Bird of Music called Reverse Migration in November; which I really wanna get my hands on! Ruff and Jam's remix of "Lark" is awesome - check it out.
