They made one album, but Edling had already started working on a second album with a different line-up. However, due to the commercial failure of Abstrakt Algebra, Edling reformed Candlemass while taking with him some of the ideas for that second album, as well as drummer Jejo Perkovic. There, materialised on the Dactylis Glomerata album. And as such Abstrakt Algebra was over. That second album, called Abstrakt Algebra II, was later included as a bonus disc in the 2006 re-release of Dactylis Glomerata.

Mats Levén later appeared as the singer of the band Krux, another band by Edling, which has a similar take on the experimentation Edling started with Abstrakt Algebra.^[1][2]
