Just got this link to a YouTube video of the Helsinki Complaints Choir, and I loved watching it! A little googling tells me the Complaints Choir is a project by Tellervo Kalleinen and Oliver Kochta-Kalleinen and gathers people in different locales — the complaints and the music are locally produced. The Helsinki Complaints Choir premiered 25 March 2006; music composed, directed, and accompanied by Esko Grunström. The music is great. Simple piano accompaniment. Great mix of several venues where the piece is performed. It’s worth watching all the way through.
