The album was remixed and re-released by Ultimate Audio Entertainment and Relapse Records in 1999 under the title "Sol Niger Within version 3.33".

The re-release contains two bonus tracks but omits several parts of the original version.

The album is a combination of complex jazz fusion elements influenced directly by guitarist Allan Holdsworth's unique guitar style and overall musical approach.

The last track, "Tathagata", is very similar in melody to the ending of the song "Sublevels" from Destroy Erase Improve.

The album features drums by Morgan Ågren and keyboards by Mats Öberg, members of the Swedish Mats/Morgan Band.
