Tuesday: Tonight, Iota hosts one prong of the WAMA Crosstown Jam for Flood Relief trident, a concert series taking place Tuesday and Wednesday to benefit the victims of Hurricane Katrina. While Jammin’ Java and Chick Hall’s Surf Club in Bladensburg are featuring buckets of bands, your buck goes furthest at Iota, where Laura Burhenn (pictured) and Gist stand out in the noteworthy crowd. $10.

For those less charitably inclined, dirty speed-punk act The Twats take the back stage at Black Cat, promising lots of loud guitar and innuendo. $5.

Wednesday: The show has long been sold-out, despite the price, but it’s worth trying to find a spare ticket to see two of music’s most influential Browns, James and Chuck, take the stage at 9:30. Dancing is required when the hardest working man in show business meets the father of go-go.
