Listen: The Belle Brigade - "I Didn't Mean It"

What a difference a few months make. L.A. siblings Barbara and Ethan Gruska of The Belle Brigade seem to have undergone a hipness makeover physically and sonically, from the fresh-scrubbed look and jangly folk/pop melodies of their fine eponymous debut to the t-shirt and flannel, bed-head style and rockingly raucous pop blast of new single "I Didn't Mean It." Appearing on the new Twilight: Breaking Dawn soundtrack (out November 8), the song jumps from the piano-pounding get-go, grabs the melody by the throat and just takes off. More DC on BB here.
