They started the band in the early 00's as Metal Skool, I was in LA back then so I've known these guys since then. It seems like 80s glam rock has been seeing a bit of a renewed interest lately, but back then, the only way to play this kind of music was to do it as a joke. So that's what they did and it worked.
All these guys are seriously great musicians though. And really good guys too boot. I'd like to see a "serious" record by them one day, that would be cool. Although it's debatable if this style of music was ever serious to begin with. It's always been tongue in cheek for the most part... But their jokes don't bother me, especially since the musicianship behind more than makes up for it.
