Oh man, this is wonderful.
In Finnish, there is an expression, "valituskuoro," which literally means "complaint choir." When a lot of people are griping about something, that's a complaint choir.
Then a few years ago a pair of performance artists, Tellervo Kalleinen and Oliver Kochta-Kalleinen, thought, what if you took that phrase literally? So they began pitching the idea, community chorus performances with texts comprised completely of what local people were bitching about.
It was a slow start, but after a group in Birmingham, England, got excited about it the concept took off. (They had reason, and much to complain about, with Birmingham sometimes called the "arsehole of England".) After their performance, the concept has spread. And why not?
I think this is awesome, and the link to the main website is this: http://www.complaintschoir.org/ They offer many resources to help you in forming a complaint choir of your own, and so many have enthusiastially responded that, well, they've hit on something.
Their site has a lot of videos of complaint choirs all around the world. Go there and see, and maybe form your own. You know you want to.
