Goa is actually a place, I believe an island in India. As far as the story goes (at least the one I was told), for some reason tons of electronic musicians and electronic music buffs migrated there a few years ago. Goa is the music that comes out of there, a trippy, complex, layered, sometimes hard sometimes not, trance. Or at least, that was what I gathered. What I would like to know, is what is the difference between Goa and Psy trance? Which is the one that's really close to ambient?
