First time I heard Lyapis Crew...good rockin' metal/ska-influenced anthemic drinking song (gonna be a lot of belligerent Belarusians breaking shit to that beat I predict)!
Slight change of pace, but here is an all-sisters Atlanta, Georgia, band that I saw yesterday for the first time (ages 12-17):
They really can play too...their harmony reminds me of the Wilson sisters (Heart):
