Calling all acoustic guitar fans...

Well, staying in the Windham Hill vein:

William Ackerman / "Imaginary Roads"

Tuck Andress, Alex deGrassi, Michael Hedges, Michael Manring and David Torn / "Guitar Sampler Vol.2"

Moving on from Windham Hill:

How about Al DiMeola, Stanley Clarke, Jean-Luc Ponty / "The Rite of Strings" (incredible all acoustic recording)

Marc Antoine / "The very Best Of"

Torcuato Mariano / "Paradise Station" & "Last Look"
Both can be found on the web under "Brazilian Jazz". Torcuato is an awesome guitar player, although his recordings are currently import only. 12 & 6 string acoustic guitar with a very emotional kinda' "feel good" sound. I have owned "Paradise Station" since 1994. I still play it at least once a week.

Well, I think I've spent just about enough of your money.

Happy listening.

Jorma Kaukonen (of Jefferson Airplane and Hot Tuna fame) - Too Hot To Handle comes to mind. Also, some of Bruce Cockburn's early releases.

Probably someone's going to say Leo Kottke but I find him way too boring.

e.

I just started to listen to The Pizza Tapes - Dave Grisman, Jerry Garcia & Tony Rice. It is excellent.

Sergio and Odair Assad "Play Piazolla"
