Beautiful guitar work. Several famous jazz players, notably Jimmy Smith (organ) and Errol Garner (piano "Misty") didn't read music, but most of today's top jazz players do. As a general rule, most 'ear' players tend to play some of the simpler forms of music such as blues, folk, and rock. Very few become 'world-class players' and almost to a man they'll tell you that they wished that they could read. Of course 'reading' means different things to different people. Reading a 'fake sheet' and playing a simple Presbyterian hymn from a standard sheet are two different things. IMO, the best musicians can do both.
