I would love some suggestions on great acoustic...

I'm sure this isn't what you had in mind, but both of the Jackson Browne Solo Acoustic albums are excellent.

Actually I have one of them and like it except for the political ranting at times. Very good music. I will check out the second. Thanks.

How about Michael Hedges?

If you're into digital file playback, you might find some recordings of interest at the Blue Coast Records website or its associated DownloadsNow site. One thing that's nice with these sites is that samples (often full length) are always provided for preview. As an example, here's an album (downloadable as standard resolution wav files) that's all solo guitar: Long Summer Days by Karen Segal

I still listen to the old Levinson "Elliot Fisk Plays Scarlatti", which is usually available on Ebay. The Sheffield Micheal Newman record is also very nice. Michael Hedges "Arial Boundaries" is good too. He plays electric, but it's very melodic. Ralph Towner "Timeline" is excellent, as is Peder Riis "Classical Guitar" on Opus3.
