Trust me buddy, what you just heard is not anywhere near Death Metal. Like someone else said, its pretty much pop music.I really wanted to see this but the music choice is BLAH. I am a fan of all music types but this hardcore death metal(most likely) is just horrible.
Errmm.. go home and try it... It will kick your ass....what I fail to understand is how hitting a tyre with a sledge hammer helps in the process of training to fight MMA?
