That's pretty awesome. If Steven Seagal can do decent at blues, I'm sure Kurt can do decent with a guitar. I've liked most of the things he's been in, and some I'd go so far as to classify as awesome, like Big Trouble in Little China and the Thing (both John Carpenter movies) - he even did passable in Soldier.
I was brought up by two people who just said, Whatever it is you're interested in, go do it. There is no winning or losing. You find out when you do it what the experience is.
