Newbie Q : don't tube amps fear everything but heat as they generate a copious amount of heat themselves?
Maybe the screens were a cheap way to give the stage a classy look?
I believe that covering the backline in white was a visual concept : trying to make the band visible by having a clean white background on stage. The gigs were outdoors and daylight gigs, So a clean white background made the band more visible to the audience.
Why the hell would the Stones play daytime, outdoor gigs? This is the band that often showed up many hours late. I've always wondered/ have been very surprised that in an era basically at the peak of their debauchery and drug use they'd agree to play outside in the blazing sun
