It looks like the 29th Street Ballroom at Spider House is now called the Spider House Ballroom. Though sometimes it appears to be spelled Spiderhouse, without a space. Whatever, it's on the corner of 29th Street and Fruth Street, adjoined to the Spider House Patio Bar & Cafe.
It's quite a nice place with multiple stages. And it looks like they are now posting events - musical and otherwise - on their home page. Music can be anything from singer/songwriters to glam rock and metal.
