Pipedown was a Northern Californian hardcore punk band with radical leftist lyrics, which was started in 1997 in Grass Valley, California. Their lyrics often remind of eco-anarchism, especially since they recommended books like the Unabomber Manifesto: Industrial Society and its Future( Theodore Kaczynski) and Deep Ecology for the 21st Century ( George Sessions) on their first album Enemies of Progress. On the same album, which was released in 2001 on Anti-Flag's A-F Records, lyrics like Tear down the factory, Tear down the limits of your life.
