This is an audio clip from a fictitious Metal band called Razor Kat! I was asked to write the music for the band and it was recorded for a claymation animated UPN series called Gary and Mike that ran about 10-12 years ago.
Razor Kat! is a seen in a few episodes punishing their audience with horrific volume and sadistic treatment from the band's Axel Rose wannabe lead singer.
In this clip Razor Kat! performs at a Bar Mitzvah and bad things happen.
Ahmet does the vocals. If you all like this one I can post some more. They are incredibly stupid but fun!
Have a look at one scene:
