If you are familiar with the show Metalocalypse on Adult Swim, the band has released an album. It has full length songs from the show plus unreleased shit. While it's hard to understand some of the thing's he is saying, the instrumentals on this are actually pretty good.
Fun fact: Brendan Small from Home Movies fame does vocals, guitar, and bass. Oh, and Gene Hoglan plays the drums.
Downloaded out of novelty, I'm actually enjoying this album.
It's released today (Sept. 25th) if you feel the need to buy it.
