One of my kids went with some friends to a "Battle of the Bands" semi-final recently. When the first band came on, the drummer broke two cymbals, both rack tom heads, and a drum mic within 30 seconds. (He turned the mic into shrapnel. It got off easy.) The guitarist broke two strings and no one could tell. The vocalist screamed off key, which was probably a natural reaction to being stuck in this band. The "sound" guy had a laptop open next to the board and he was using Google to search for instructions on how to mix audio.
The interesting thing (to me) is that this was in the semi-finals, meaning this band had already beaten somebody. How did that happen? I mean, when a truck full of geese is hit by a truck full of angry leprechauns, the result is far more musical (and much more entertaining) than these guys. How bad was the losing band? Given enough random notes, the odds were that, someday, a few of them might land in the same key.
Some people elevate tone deafness and self delusion to an art. It's interesting to see that there are, apparently, more of them than the network showcases on America's Got Talent*.
