Similar to Jade Warrior "Waves/Eno "Evening Star"

Popol Vuh-Aquirre, Einsjager & Siebenjager, Hosianna Mantra, and Spirit Of Peace.

Popol Vuh are considered to be spiritual however, these 4 titles cross paths with the 4 Jade Warrior titles I've mentioned above. The pieces "King Minos" sounds quite like the band Jade Warrior from the Island period.

Hiroki Okano- Rainbow...over the Gypsy Hill.....find a used copy on Amazon.

Many of the artists on the Celestial Harmonies label cross into the "Waves Part 1" sound. Try ASIA MUSIC for an introduction to these artists.

Steve Jolliffe ....ex-Tangerine Dream member and his early releases will surely guide you through that realm. "Warrior" and "Journey Out Of A Body" which features Tony Duhig from Jade Warrior on guitar.

Soundscapes from the early Mike Oldfield touch upon the sound and stretch out between 5 to 8 minutes sometimes. Sections of Tubular Bells featuring Jon Field from Jade Warrior on flute. Also Hergest Ridge and Ommadawn. Sections of Stomu Yamashta's music. Only early titles. Red Buddha Theatre features a piece titled "Mountain Pass" which says it all for me and sections of "Sea & Sky" and "Tempest" which are later releases. 

You will never find music similar to Waves/Eno and not in the sense that it would ever be exacting. Mostly it would be sections of other band's pieces that are reminiscent in vibe and sound. If there are other artists that run a much closer or similar sound, I have yet to discover them.
