I first learned of Patrick Costello's Pik-Ware Publishing from his Creative-Commons-licensed The How and the Tao of Old Time Banjo. Now he has launched The How and the Tao of Folk Music, the first folk music instructional podcast that I have ever come across. This is a great resource for people learning old-time banjo and guitar, as he is putting a new tune up almost daily.
