Abstrakt Algebra was a Swedish experimental metal band with influences from Doom Metal and some Power Metal that was founded in 1995 by Leif Edling after the band Candlemass fell apart. They made one album (their s/t), but Edling had already started working on a second album with a different line-up. However, due to not having any commercial support, Edling reformed Candlemass while taking with him some of the ideas for that second album, as well as drummer Jejo Perkovic and as a result of this, Abstrakt Algebra was over.
