Hi, I'm new both to the forum and to this music. I really like these musical genres, but unfortunately I know just a few artists, like Shpongle, Hallucinogen, Aes Dana, Shulman, Astral Projection, Infected Mushroom...and a few more...maybe... I'd like to know other names from the Goa, Psy, Ambient, Chillout and such styles. I don't even know the bigger names, so... Any suggestions / recommendations will be appreciated. (Other great websites related to this music...?)
