Prince and the New Power Generation, leaning on a music stand that apparently ruins their performance. You see the big ol' music stand at ~ 1:48-2:02, 2:45, 3:53-3:58, and again at 4:17 (as the crowd goes crazy).
A music stand or prompter isn't automatically a problem, and it's obviously not the line between a pro's performance and a hack's. It's just another stage tool. If it serves a need on your gigs, you put in the work to learn to use it deftly.
If you haven't noticed charismatic stage pros using prompters or stands, it's b/c the ones who use them well have put in that work.
That was smokin'!
