Alright, to start I'd like to state that this band is fictional. The music isn't but the band, "Dethklok" is fictional. This isn't to say that the music produced by "Dethklok" is fictional, jus tthe band. The band is actually Brendon Small and Gene Huglan. Two people.
If you've ever heard of the show Metalocalypse that runs on Adult Swim every Saturday at midnight then you'd know remotely about this band because Metalocalypse is the show allabout them and their misadventures as the world's greatest band.
Anyway, the standard Dethalbum blew me away, it had all of the most memorable songs from the show except they were extended and more detail went into making them. So, it's fantastic but the Deluxe Dethalbum offers more, allot more actually. Allot more than I would've excepted, the original Dethalbum contains 16 songs while the bonus disc on the deluxe album contains a bonus 7 songs with extravoice skits from the members of Dethklok (Natha, Toki, Pickles, Skwisgaar, and Murderface). So, if you've ehard of the show or band and haven't already got this magnificent gem it's recommended that you pick up a copy asap, you won't regret it.
