The folks in Plaza Midwood know how to party. This Saturday, you'll want to mosey on over to Petra's for the Plaza Midwood Spring Party. Hosted by local musician Jon Lindsay, it's set to feature a load of live music (by Lindsay, Jay Garrigan, Miles Swartz, Anna Bullard, Eston Dickinson and the Swaggerettes, Jack The Radio, Old Bricks, Jon Lindsay, The Catch Fire, The Loudermilks, The Houston Brothers, Jeremy Shane), visual art (by Kelly Keith and Alexis Owen) and a dance party with a guest DJ. But, no outdoor fest is complete without the cookout, right? No worries; it'll be there. But because the economy still sucks, condiments are the only things being provided. This is strictly BYOM: Bring Yo' Own Meat. $5 in advance; $7 at the door. 7 p.m. Petra's Piano Bar & Cabaret, 1919 Commonwealth Ave.
