Widespread Panic has remained relatively quiet this winter while working on its next studio album. However, the jam-titans will emerge from hibernation this spring for another round of tour dates. While Spreadheads await a full itinerary, the group has confirmed a pair of shows at Raleigh NC’s Alltel Pavilion at Walnut Creek On April 21 and 22. Widespread Online Ticketing begins tomorrow at noon, while March 11 has been set as the show’s public on sale date.
