This is one of the best ritual "ambient" albums I've heard in recent years. Apparently it is their first (dark ambient) release in something like 20+ years, and it is brought to us by Steinklang Industries. Tribal Zone is a very old school sounding affair, with layers of extremely hypnotic evolving drones and tribal percussion. They also use a lot of asian voice samples/chants which fit perfectly. Very old world, very atmospheric, very dark. If you like ritual and/or tribal ambient music than this is a must buy!
