Eon Project - Brain Filter in 1998 Posted September 12, 2009 It's clear who contributed what to UX project: Slide's Unstable is plain harsh dark psychedelia, while EON Project is very rhythmic, layered and atmospheric music. This album holds my interest from start to finish, something that Unstable could never do. I like the industrial sounds mixed with trance here. Chris Kylven has a lot of diversity in his music. I think he's underrated. He's the reason there is some soul in the Ultimate Experience album. 8/10 from me.
