This year marks the 30th anniversary of PineCone, the wide-ranging Raleigh-based traditional music programming organization. For three decades PineCone has been an essential organization in the education and promotion of bluegrass, blues, folk, Cajun, gospel and other forms of roots music. Besides bringing more than 30 concerts a year to Triangle audiences, PineCone has joined with the International Bluegrass Music Association to bring the Wide Open Bluegrass Festival to Raleigh Sept. 30 through Oct. 4. As a prelude, the City of Raleigh Museum hosts the exhibit, “Face of Folk: 30 Years of PineCone.” The exhibit, which runs Friday through Dec. 31, celebrates PineCone’s achievements and the art and artists it has featured through the years.
