Portugal. The Man are running an extremely cool campaign on Earth Day to get the message out to save the endangered Sumatran Tiger. The band made 400 limited vinyl 7”s that have been designed to degrade over time. The point, of course, is to keep the music alive by sharing it, just like the band hopes to get the message out to help keep the Sumatran Tiger alive. Check out more details on the campaign here and stream “Endangered Song” below after the jump.
