The MAHA Festival folks just announced that they’re hosting band showcases May 24 at Slowdown and June 24 at The Waiting Room to pick who will play the Kum & Go local stage at the festival July 24. Satchel Grande already has been selected to play by the MAHA Committee. I comment on why I think the showcases are a mistake in my column, which will be online here tomorrow.

The bands competing at the May 24 Slowdown event are Betsy Wells, Dim Light, Flight Metaphor and Noah’s Ark Was A Spaceship. Good luck to all four. My vote would go to Dim Light, but I already know that Noah’s Ark Was a Spaceship will win this competition — after all, they played at MAHA last year.

Clarification on yesterday’s blog item: The name of So-So Sailors’ drummer is Dan Kemp, the former drummer from Bloodcow. And Dan McCarthy plays Wurlitzer in S-SS, not bass, as reported.  Oops. Sorry.

Tonight at The Waiting Room, it’s rock-pop-meister Butch Walker and the Black Widows. Read Chris Aponick’s story on Butch online here (or in The Reader), where he mentions that Walker has produced albums by Weezer, Pink and Katy Perry, among others. Walker’s 2006 album, The Rise and Fall of Butch Walker and the Let’s-Go-Out-Tonites is one of my faves from that year, thanks to its nod toward classic cock-rock. I don’t know what he’s been up to lately, but I’m sure it’s no good. Opening is Madison Wisconsin’s Locksley, an unsigned band that’s played on Conan O’Brien, Kimmel and spent a couple weeks performing as Ray Davies backing band. Tonight is Locksley’s first date on the Butch Walker tour, so it could get interesting. $15. 9 p.m.
