That was a visual I did not need. I was going to guess scratching the stage. Back in the day I never gave a thought to hauling gear down a flight of stairs and out to the trucks at 3am. The worst part back then was not noticing the spilled drinks (or worse) on the cable you are rapidly rolling up. Probably not nearly so many cables today. As a keyboard player I had two suit cases full of cables and power supplies. The good old days . . . you can have 'em.
I hear ya on the cables, and there's still about the same number as in the old days, although there's no longer a need for a snake, since everything plugs into a stage box that's also the digital mixer. The mixer is then controlled via WiFi on a tablet or other similar device. I normally run sound from the stage (a tablet on my mic stand), but lately we've also had my buddy Art sitting out in the audience with a spare tablet making minor adjustments and cuing various delay effects where needed. With the WiFi setup, I can run FOH (with Art's help) the drummer Donnie can run monitors from his seat, and the other two guys can also tweak their own monitor mixes via tablet or phone. With all the technology these days, it's a great time in history to be a musician.
If you had told me back in the '80s that you could buy a 24 channel stereo mixer with graphic and parametric EQ on each channel, 8 Aux sends (also with separate EQs), as well as a boatload of assignable effects, and have it all fit in a box not much larger than a loaf of bread, I would have thought you were crazy. The fact that it can be had for less than $1000 is even more crazy. It still boggles my mind that we can power a full band off a single 15 amp 120v circuit. That includes guitar amps (modelers, actually), a few LED stage lights, and enough clean FOH and monitor speakers to easily put out 105 dB. (We don't run quite that loud, but we can.)
