Hudson River Sloop Clearwater, a non profit organisation whose mission is to preserve and protect the Hudson River have launched the ‘Clearwater Build-A-Song contest’. The basic idea behind it being using Online Music Collaboration to build a song to help combat climate change. There is already a chorus and music prepared for this song but the contest is to find four verses to go with this chorus. Participants can follow a link on their site to grab the chorus and music and go to Soundcloud to download the existing audio files. Deadline for submissions for the contest is March 20th. The Clearwater organisation was founded by folksinger Pete Seeger 46 years ago! Follow link here for an article with some background and go here to enter the contest.
