It's actually part of an international art project.
(Speaking of complaints, I can't make out all the lyrics from the Birmingham complaint choir, and the music isn't as good as the Helsinki choir's.)
Maybe you can get a complaint choir in your city--I wouldn't mind having one in PHiladelphia.
Update: I'd accidentally put http://www.youtube.com/watch?v=lNMEdBhvHK8&eurl= at the top--it's actually an animated video of Vote for the Instant Karma Party. Pretty good (I'm especially fond of the little bowtie on the horn), but not as wonderful as the Helsinki Complaint Choir. ObComplaint: Utube has uninformative urls.
