Dethklok is a virtual death metal band created by Brendon Small and Tommy Blacha for the television show Metalocalypse. The band is sometimes cited as an example of "comedy rock" on par with bands such as GWAR or Spinal Tap, though the overtly comedic aspects of the band are usually reserved for show episodes, while the music itself is relatively straightforward extreme metal. The band's less common typeset, Dëthkløk, includes heavy metal umlaut.
Their debut album, released September 25, 2007, was entitled The Dethalbum. Creator Brendon Small wrote the lyrics and music and also performed the guitar, bass, and vocals; former Death/Dark Angel/Devin Townsend/Strapping Young Lad drummer Gene Hoglan performed drums on the album. The album debuted at #21 on the Billboard Top 200 list, making it the highest charting death metal album ever.
