Astral Projection's roots go back to SFX, formed in Israel in 1989, which comprised Avi Nissim and Lior Perlmutter. Their first single in 1991, Monster Mania, was successful, and they moved to New York. Moving back to Israel they changed their name to Astral Projection and produced their first album in 1994. Up to 2004, they released nine albums, and a new one is due out in 2010. They perform live extensively around the world.
I have had Astral Projection on here before, but this track is awesome; kind of defines Goa Trance. You might want to try other of their tracks like People Can Fly and Dancing Galaxy, with its references to Frank Herbert's Dune.
