Query: Not a good step in the evolution of guitar music.

As a guitarist myself and someone who has studied many styles over three decades of playing, I've heard and played with some amazing players. The guitar craft style and its practitioners have some nice stuff and good technique within the realm that they explore, but they are really far from being complete guitarists. Any great classical musician and/or teacher likes to use this kind of playing as an example of something to avoid falling into. My teacher did. Hardly a shred of passion or personality to be found in even the best guitar craft musicians... and their technique is actually not that amazing. I've played with players that can play far better in every respect. Sometimes we would sit around and imitate the Fripp technique just to illustrate how far from elegant that kind of playing actually is...
