Liquid Mind's (a k a Chuck Wild) career retrospective Relax: A Liquid Mind Experience.
You know, if you really listen to Chuck's music intently, esp. on headphones, you hear all kinds of stuff going on...gentle yet energetic sequence notes, Ray Lynchian-type synth work, all manner of electronic textures, etc. So many people dismiss his music as nothing but lush flowing new age music, but it's more sophisticated than that. Besides those more overt synthesizer textures and noises in the background, he also actually varies the main melodic instrumentation a lot from album to album, sometimes featuring strings, at other times chorals, or he may switch to woodwinds or a solo wind instrument. I remember interviewing him way back in 1997 and he made it clear how much care and quality he puts into his recordings, spending (IIRC) about 80 grand making each one. The mix on his albums is always textbook, again IMO.
Anyway, while a person might consider his albums as being overly similar or even monotonous, they're really not, IMO. As pure background music, though, they are excellent soothing "ambient" music ...almost too relaxing in fact (I'm listening on headphones at work and it's hard to concentrate, to be honest).
