Warpaint!!! They were love at first listen for me, and quickly became my 2nd favorite band. Great combination of darkness, shoegaze, indie. Also a great live jam band, they add a lot of jams to their live songs. New album should be out in January.
Sixpence None The Richer. Forget the "Kiss Me" pop stuff, their earlier music is darker and rockin'. Check out "Musings", "Falling Leaves", "Angeltread", "Love, Salvation, the Fear of Death".
