A few things…
I am a musician. I have been paid to be a musician many times. One summer, I made it on the Dr. Demento Funny Five!!!
Most of what I have done in the past have been late, paying (by door or cover) gigs with a professional sound tech with a professional sound system. Those were, by far, the loudest gigs I have ever played. However, WE were the reason folks were there, and the places were (generally) not restaurants.
In my older years, I have taken to playing the Fat-Old-Man-on-a-Stool gigs mentioned upthread. “Peaceful, Easy Feeling” is one of my mom’s faves, although if she isn’t there, I am not playing it. It’s boring as fuck.
My setup used to consist of a couple JLM PAs and a six-channel powered mixer. Nothing crazy. I’ve since upgraded to a Harbinger “stick” PA, which allows EVEN LOWER volume with better room carry. That was on purpose.
No one is there to see this ogre warble out another of the same-old shit. I know that. Sometimes, I play some of my filthy parodies to see if the (age-appropriate) audience is listening, but otherwise, I stick to the list, politely take requests, allow audience members to grab a mic, and dog-willing, if the audience sings along, soak it in for the joy it brings. Live music CAN be wonderful, and engaging, and sometimes, it creates special moments.
All that being said, having pretended to be a rock star for the better part of my 20s, my tinnitus is dreadful. As I sit here, right now, with a front blowing through, it sounds like a lifeguard is on my porch blowing a whistle at me. It’s ever-present, and it sucks. Background noise makes it way worse.
Recently, my wife and I were at a wedding, and when the music started, the DJ had it at “Who Concert” levels, and we were RIGHT beside the damned speaker. Beyond that, it was all “New Country,” which sucks. We ate and left. It was also in a barn, because that is where they would get the best pics for their instas, or something… I really can’t stand most young people.
So, I get it. If I see a busker with a guitar on a sidewalk, that person is getting some of my money. Music, and the performance of it, speaks to everyone. And for me, unless it is abjectly terrible, I support it. It takes brass balls to get in front of a crowd and put your shit on the line. Trust me.
