This is the Milli Vanilli of metal.
I'm sure this is every band's worst nightmare when lip syncing or using backing tracks. Lordi is a Finnish metal band that's been around since 1996. This goofy masked band was performing at a huge music festival when their backing track started to skip. Looks like this happened back in 2006 and just surfaced a couple months ago. This is what you get when you can't pull it off live.
