Wikipedia calls it an "interpretation of out-of-body experiences (OBEs) achieved either awake or via lucid dreaming, deep meditation, or use of psychotropics." Astral Projection is also the name of one of my favorite artists in the Goa Trance scene.
Astral Projection has played here in Florida at the Blue Cafe in Aventura, and I had the honor of opening for them. Their members, Avi Nissim and Lior Perlmutter, are based in Israel and have released over ten albums since the mid nineties mostly under the Phonokol label. There is an inspiring aura to their style and infectious euphoria buried within their rhythms.
Not many mention Goa Trance without mentioning Astral Projection within the same conversation. However and unfortunately, among the growing numbers of elitists in the Psy Trance scene, they have been dubbed as sell-outs because they have allowed themselves to change their sound over the last couple years, although not as drastically as Infected Mushroom (of which I will speak of sooner of later)
These elitists, I feel sorry for them but also empathize with their plight. Music is a very personal thing, and we feel that when we find something that so strongly represents our identity, we become very possessive. But who are you to tell the creators of art what to do? It all comes down to whether art belongs to the creator or to the community.
