Narada and Wyndham Hill have both put out compilation CDs with many different players on acoustic. The WH ones are done with Taylor guitars being a major sponsor. Excellent stuff. Pat Kirtly is on some of these. Jim Volk is a tremendous acoustic guitarist. He recently won several levels of competition sponsored by Guitar Center.
I like so many (Kottke and many others) but I just saw Joscho Stephan, a gypsy jazz guitarist from Germany who play Django style. He is the most amazing guitarist I've ever seen. I've seen a few good ones over the years too!
