Seen Steel Panther nine times now (going back to when they were Metal Skool)
Their festival show is totally different to the club show, but still worth seeing. Festival show is mostly their original material, the club show is mostly covers with more audience interaction (and always a celebrity chucked into the mix, and often some high wire guitar solo acrobatics...).
What sucks, is that those nine times Ive seen them, would have cost less in total than this one ticket to Soundwave...
