Australian Magpie Trio Perform Impromptu Experimental Noise Concert

This is a video of Australian magpies R2-D2, Baldy, and Mrs. R2 singing to produce what can only be described as a terrible sound. It’s like electronic distortion. When they sing individually they actually sound pleasant, but when they get the whole band together it’s just a cacophony. That said, I’ve gone to see friends’ bands that were ten times worse. I’m actually supposed to go see one this weekend, and I’ve been begging sniffling coworkers to cough in my mouth all morning so I get sick and can’t make it.
