It depends to some extent on the audience's love, need or want of 'visual entertainment'. For my part (and quite used to being in a majority of one...), I have little time (read: none at all...) for poncing about , running hither and thither, rehearsed histrionics and/or posed attitude. Seeing Shakti, for instance, was not a 'visual' thing; one could easily close one's eyes and enjoy the moment. Seeing the exchange of looks, and evident complicity between the players, was quite enough 'visuals'. Might as well listen to the CD..? Not really (although I do that, too...), more of a communion with the soaring output of those great talents. Just one example of soooooo many (Royal Philharmonic, Grateful Dead, Soft Machine, Joni Mitchell... The list is long...). Memorable for their performance as musicians much, much more tha for any visual 'show'. Yes, I've seen many splendid animated acts, too, but the real 'crackers' don't need such to entertain me. Keith Emerson (The Nice...), with his daggers in the keyboard..? For all its merits, I preferred folks playing in more sober fashion, such as King Crimson, or Fairport Convention. No need for pantomime 'gimmicks' if one is really that good.
Just my tuppence-worth.
