Think the rolling-skating revelers in the Rapture’s “Whoo Alright — Yeah . . . Uh Huh!” video look like they’re having fun? They’re not just faking it for the video; the song really gets the dance floor going. See for yourself at A Roller Skating Jam Named Saturdays, the B-Side Liquor Lounge‘s newest weekly party night. Every Saturday, misterbradleyp spins party music — bouncy 4/4 rock, rap, and dance tracks from bands like Montreal, Good Shoes, Matt & Kim, Shiny Plastic Guns, and the Raconteurs. You can’t actually skate, but the club has beer. It’s a pretty good trade-off.
