Hi,
The list that was mentioned is so full of merde it's not funny.
If meditation and relaxation music you want, you do not want lyrics or things that have a tendency to distract your ability to meditate as words ALWAYS will.
If you want to hear pure meditation music, you might want to start with the original, Hemmings and Wolff, in the album "Tibetan Bells", and if you want to graduate you can do Frank Perry's "Deep Peace" and then "New Atlantis". These are all Tibetan Bells.
Many others out there:
(Make sure you know what "meditation" is!)
(Meditation is about you learning your own flow, not flowing/tripping with someone else's.)
Popol Vuh - Almost all their albums although the last ones got a bit more familiar, than the long extended moments of quiet, before.
Klaus Schulze - To an extent - Music for adept meditators only, these tracks are often 30 minutes long or more and they are a very detailed inner trip that is very relaxing and enjoyable if you are not stuck on pop music.
Bryan Eno - Started what became known as "Ambient Music" in the early 70's. One of the first albums that were out, was actually a Fripp and Eno album called "No Pussyfooting" and it was excellent, although no one, at the time, could handle guitar "trips" as the only title possible for what this is. His explorations and experiments create a lot of inner quiet that is very good for meditation.
David Parsons - Some meditation music that has taken the winds in the Himalayans and turned them into keyboard work and it does have some local chants and such. But it is massively pretty.
Tangerine Dream - very nice flowing stuff in the early days (Zeit/Atem/Phaedra). Harder to interpret later as it became more "theme" oriented, and anything that is "theme" oriented will break the meditative state right away -- it prevents your own flow by attracting yo to another flow.
Keith Jarrett - Some of his piano explorations, are inspired by Gurdjieff (sp.). The connection might be a bit more difficult to investigate, but it has to do with the freedom of the playing until it resolves itself into a piece of its own.
Roedelius/Rother - The famous folks behind the electronic inspired music, on their own, are very experimental and trippy. Cluster/Kluster also fits.
Paul Horn - In the late 60's a few albums showed up inside the Taj Mahal, and other places. Paul played his flute to wonderful natural echoes and brilliantly recorded. One of the best albums of music ever recorded. He did others as well.
Stomu Yamash'ta - In the later days, after "GO", he did some spiritual work that was not quite theme oriented and was quite pretty.
Kitaro - Despite his new age connection, he did have some wonderful music that not many folks listen to. It does have a nice inner quiet.
Deuter - German guy that produced some very nice albums. His popularity kinda died some when his group got in trouble in America (Oregon), and his work, kinda disappeared for a while. Many of his albums are wonderfully well done and very quiet listens.
I have not learned how to meditate with the hindu masters like Khan and many others, and I am not sure why, though I love some of their music. Khan's stuff with Jan Garbarek is magnificent and truly inspiring. Likewise the "ragas" that Egberto Gismonti had done in the early days with his guitars. These were priceless and very quiet on the inside, although they tended to place your imagination in the jungle, without the sounds.
