Artist Biography Carbonized were a Swedish death metal band formed 1988 in Saltsjöbaden. The band was formed by Lars Rosenberg in 1988, with Dismember vocalist Matti Kärki. Joined by drummer Piotr Wawrzeniuk, the trio was completed by Therion's Christofer Johnsson, who originally agreed to only perform session guitarwork but eventually became a full-time member.
Quite different from anything that any of the members would become involved in later, the three albums ran the gamut from psychedelic infused grindcore on For The Security to dischordant jazz-metal weirdness on Disharmonization to something apparently stranger and more avant-garde on Screaming Machines, and described as "the worst of Sonic Youth, Syd Barret era Pink Floyd, old Black Flag, and Voivod" by Christofer Johnsson. Both Rosenberg and Wawrzeniuk were featured on a few Therion albums through Christopher Johnnson, and they also paired up in the doom band Serpent.
