Jan Axel 'Hellhammer' Blomberg (born August 2, 1969), is a two time Spellemannprisen award-winning black metal drummer from Trysil, Norway. He is most well known for his drumming with the band Mayhem, with which he began his career. Blomberg was already part of Arcturus at the time, the band he founded along with Steinar Sverd Johnsen. He is endorsed by Sabian Cymbals, Axis Pedals and Pearl drums, though he has been known to use Yamaha drums as well.
Before he started playing music, Blomberg worked in a psychiatric hospital. He joined Mayhem in 1988, following the departure of the drummer and founding member Kjetil Manheim. In addition to Mayhem, one of his long-standing bands was the avant-garde metal band Arcturus, which he formed with Steinar Sverd Johnsen in 1987, originally under the name Mortem, and broke up in April 2007. He has since joined and sessioned for numerous bands.
