well it ain't pure ambient, thats a fact for sure... define it as chill/psy-chill or whatever, but definantly it ain't ambient, sorry to dissapoint you... pure ambient are soundscapes/drones etc.. and oh i didn't say hallucinogen in dub is a crap album, its quite nice, but i wouldn't define that as ambient either... someone said that ambient is psychedelic, well perhaps at some points it can be.. but all the ambient you probably have heard is the stuff that comes from producers within the goa/psy scene.. i'd rather define that as psymbient/psychill or whatever... not ambient, you want pure ambient? take a good and _DEEP_ listen to this for instance:
Dighom - A1: Kunthai 8:51
Now, that was amazing, was it? (some people might find it boring though because 'nothing happens' bla-bla.. listen to this under the right circumstances... either while induced or while in bed, lights out, and have a nice journey...) Either way it has NOTHING to do with full-on at all.
IF you liked it however, go here and get the rest.
