Inner Mounting Flame is to me the very best jazz/rock fusion album there is. Again, sounds best on Japanese record.
Visions Of The Emerald Beyond by John McLaughlin's Mahavishnu Orchestra is great too.
Cielo e Terra by Al di Meola is a unique acoustic guitar album - mesmerizing enigmatic mindscapes. Sounds good even on cd, record is much better of course. Analog recording and mastering.
