This question is apparently harder to answer than it first appears.
I have a fair number of Michael Hedges albums, but very few by other acoustic guitarist and none in the specific areas you are asking.
However, many guitarists have released acoustic albums that are not in the genres you don't like (if that makes sense).
Here's a list of possible guitarists, perhaps someone else can recommend albums by them...
Al Di Meola - Elegant Gypsy
John McLaughlin; Shakti
Philip Catherine - Guitars
Steve Hackett - Bay Of Kings, A Midsummer Night's Dream, Metamorpheus
Steve Howe -
Gordon Giltrap -
Fred Firth -
Robert Fripp; The League of Crafty Guitarists -
