"Peccatum was formed by singer Ihriel (Heidi Solberg Tveitan), her husband Ihsahn (of the well-known black metal band Emperor), and her brother Lord PZ. The group has released five albums since their inception in 1999. Lost in Reverie, released in 2004 after Lord PZ's departure, demonstrated a change in a more classical, avant-garde and musically opaque direction.
Lost in Reverie and the 2005 EP The Moribund People were both produced under the label Mnemosyne Productions, owned and operated by Ihriel and Ihsahn themselves.
On March 4th, 2006 Peccatum split, leaving room for Ihriel to continue with Star of Ash and Ihsahn to work on his solo work." (Taken from Peccatum's last.fm page)
Peccatum play some very interesting and varied Avant-Garde Metal... I'm not quite sure how to describe them but if you like Avant-Garde, Emperor (parts of it are Blackish!), or Ihsahn's solo project you might like it or might as well give it a try. If one album doesn't do it for you, check some of the others. You can't listen to one and understand them all.
