The local indie rock act Biitchseat celebrates the release of its sophomore album, Float, with tonight's show at the Grog Shop. With the album, the band takes the sounds of ‘90s acts such as Liz Phair and the Breeders and tries to build upon those sounds to produce something appealing to twentysomethings. The concert begins at 8:30, and Runaway Brother and Wife Patrol open. Tickets cost $12.
