Whilst I would agree that the guitar playing technique demonstrated on the various linked clips is very impressive, I'm not so sure about the quality of the actual music. Very limited harmonically...the tunes I listened to contained nothing much more than highly decorated tonic, sub-dominant & dominant chords (like playing C,F & G or E,A & B) & any enduring melody was conspicious by its absence. For me, these guitarists created a dazzling display, but ultimately left a void where the Music should have remained for me to savour.
