Stuart: The "Dreaming The Magic of Your Maya" LP was indeed released back in 1968 under the name Princess Flower and The Moon Rays. The LP is noted in Patrick Lundborg's Acid Archives book and was reissued by Wah Wah circa 2012.
The main guy behind the LP is one Loren Standlee, who had connections to the NYC avant garde art scene back in the day. The original LP is essentially a private pressing with only a very small handful of copies ever turning up in the New York City area.
Daevid Allen is one of two guitarists credited on the LP, the other being one Fej Mornin who, it is suspected, might be Allen in disguise. "Between Spirits" is the only track to properly credit Allen.
The 2012 reissue has an extra LP of material recorded in 1970 at Apostolic Studios in NYC. The reissue also has an insert featuring an interview with Loren Standlee, which is very insightful regarding how the LP came into being.
As for the actual music? Let's just call it an interesting and unique curio from the era.
