A handful of years ago we were regulars at open mic in a suburb of Sacramento. Some of the performers were excellent musicians and singers; real artists.
Some, not so much.
One night two young boys, the older probably 15 and the younger 10 or 11, came in with their electric guitars. They used a recorded rhythm section backing track and played along and sang.
From a purely musical perspective, they were not very good.
I had seen something, though.
