You're gonna hear this guy roar.

This church band  was doing a rendition of 'Roar' when the guitarist flipped out. Everything seems to be going okay when he interrupts the performance, chastises the rest of the band and then destroys his guitar.

You know, Perry started out singing church music before turning into pop's princess. This guy may have started in churches, too, but he's acting more like he should be in a death metal band, wouldn't you say?
