Masayuki Kurihara and Ray Castle are two, bar none, pioneers of the international goa trance scene, but their input in its general development is beyond words, anywhere from Japan down to Australia.
That said, their 1995 debut, and thus far only collaboration, under the name Masaray, is a heavily sought after album hailing from the far away lands of Australia, and released under the legendary Psy Harmonics power house label.
Now, "Cosmic trancer" is an album which today, despite some great and challenging music, is very dated. In fact, if you're not a die hard old school goa trance addict, I'd strongly recommend you spending your money elsewhere.
The music is not easy to sink into. Not as nearly as complex and layered as most highly venerated classics from the era, the manner in which these two producers manipulate with what they had at their disposal is just awesome. Tracks like the opener Cosmic Trancer, and the last two tracks, Scorpio Sun Eclipse and Time Traveler Of Trance, are timeless classics, great psychedelic trance monsters from an era when the genre was pure, undilluted and was not concerned about fascinating the masses and lacked the burden of the often dissatisfied and grumpy fans which would plague the scene during its later years.
It's a mile stone in goa trance, yeah, a timeless classic like some of its contemporaries it may not be, but for hisotrians of psychedelic music, this is an essential find and purchase. However, if your main associations with psy trance are recent(er) arrivals such as Zenon Records, Parvatti and what not, you would really want to listen to this one prior to making the purchase. Good luck finding it, though.
