I discovered MVYRadio (Martha’s Vineyard Radio) when I was unable to attend the 2008 Merlefest Celebration in Wilkesboro, NC.  Remembering their advertisements at previous Merlefest events, I checked them out online and found they were streaming live from the festival and had a rich archives of performances from past years.  Check out the archives section and you’ll find performances from a number of great festivals.
