CAB Coffeehouse Performance: Andy UlsethMay 6, 2009 at 89 p.m.

Time: May 6, 2009 at 89 p.m.

At the 318 Cafe, Andy Ulseth bemusedly told the crowd, "Let me make it clear right up front: I used to sing with Casey Carlsonof 'American Idol,' but she won't be here tonight." He wasn't kidding. He and Carlson were Eden Prairie schoolmates who used to perform together, but now she's out in Los Angeles pandering to Simon Cowell. Set to headline the 400 Bar Feb. 27, Ulseth is doing just fine on his own with a melodic, boyish but brainy brand of acoustic rock exemplified by his terrific Fleet Foxes cover.
