I guess they must be playing the back stage, since Beauty Pill is playing the main stage on 4/17. I recently picked up "Songs For Polar Bears" and like it a lot.
I definitely want to check them out, but I've missed Beauty Pill the last couple times they played and swore that I'd do whatever was necessary to see them next time around. Throw the Fleshtones into the mix and there's just no way to hit everything that weekend.
April is turning into another month jam-packed with shows.
