It's only one quartet (the 4th) not a set, but the Zehetmair quartet recording is stunning. They are in some ways the contemporary equivalent of the classic era Juilliard quartet - fiercely individual and orginal, astonishingly virtuosic and treat modern and classical repertoire as the same sort of material.
I stumbled across autographed CD's of Joey DeFrancesco - 'Project Freedom' and Buck Hill - 'Capital Hill'. Autographs don't really do anything for me, so If either or both of these are of interest to you, let me know what you would be willing to send me that consider a fair trade for them, and we'll see what we can get done. Both autographs are on the front of the CD booklets. The DeFrancesco is his signature in black sharpie, the Hill says "To Woody Buck HIll 1992 in black thin line sharpie. PM if interested, thanks.
