It was fun to listen to hear him sing a few songs--with this magic piano that somehow made funky beats while he played and looped his voice singing different things. Really, I think it was magic. Also, I thought he was wearing a tacky Christmas party shirt when I first saw him, but upon closer inspection, it was just a normal, plaid, hipster shirt.
Then, I got to go home and watch a very sweet episode of Glee, featuring Chris Mann as "Warbler #6." (Kurt breaks my heart over and over.) Check Chris out, he's in the back row on the right during "Teenage Dream."
But really, he's very very talented and it was really fun to get to see him. Twice. In one day. You can go here to see if he's playing anywhere near you. If he's not, then hopefully you can catch him again on Glee!
