In ways its all about show...Kiss. In other ways its about music......Ronstadt. I prefer the music emphasized show.... Dylan/Knopfler etc. I just saw the Tedeschi Trucks band and believe me it was ALL about the music. I do understand the need for show band and their place in R&R. BTW Tedeschi Trucks....one guitar all night for Derek and one guitar all nite for Susan....the only guitar changes was the Bass player he had 2. AMAZing concert.
