Our friends at RadiOWS are back with another free-format radio show produced by New York Occupiers. This time, they're taking listeners through a brief history of May Day, so get ready to learn.

RadiOWS works to amplify the message and voices of the Occupy Movement through reliable news coverage, thoughtful discussion, original music, skits and whatever else they can think of to inspire, amuse and engage listeners. Check out their previous podcast, and of course, if you're good with audio and want to get involved, contact RadiOWS.
