Jim Croce is amazing and I love him, I just want to nitpick a slight bit in that there's actually two guitars in most of his songs, with the second guitar player being Maury Muehleisen, who we also sadly lost in the plane crash that killed Jim Croce. The beauty of their songs is that the guitars blend together so effortlessly that it's hard to tell it's more than one.

Mark Knopfler is absolutely incredible. He's got an instantly recognizable sound and has a knack for just making good music.

JJ Cale is another good one. He's one of those guys that has written a lot of really great songs that other artists have covered, but never had any huge hits with any of his own songs.
