ALTERED AEON was formed in 2001 when Henrik Ohlsson (Theory In Practice, Mutant) presented a bunch of songs to Kjell Andersson (Azotic Reign), but back then the band was called THRAWN. They both agreed on the approach of the music and continued working with Henrik`s musical ideas, building a similar vision that they strived to manifest in the music and lyrics.

Due to working with their additional bands it took quite some time before they had developed the sound they wanted for ALTERED AEON. But once they decided to concentrate fully on this band, their other bands being pushed down the priority list in favor of ALTERED AEON, something truly unique emerged musically and lyrically.
