Metalocalypse Season 4 Kicks Off! [VIDEO]

My favorite fictional metal band returns for a fourth season on Adult Swim!

"Metalocalypse" will throw down the start of the 4th season on April 29th at 11:15pm. the 4th season has once again guest voices by Soundgarden and 3 Inches of Blood. Along with stand-up comedian Patton Oswalt, Dweezil Zappa and Jon Hamm of "Mad Men".

Dethklok is the name of this fictional band that "Metalocalypse" is based on. With lead singer Nathan Explosion giving a head to nod to George "CorpseGringer" Fisher this is my favorite show on TV.

Get familiar with the "Most Brutal Band In The World" in the world Dethklok.
