Old Crow Medicine Show, Dave Rawlings Machine (Featuring Gillian Welch), The Felice Brothers and Justin Townes Earle will share the billing and the stage for the Big Surprise Tour which has announced nine east coast dates in August. The shows will consist of two 90 minute sets during which, (i)n a free form ramshackle flow the bands and artists will share the stage, taking part in each others songs, resurrecting old standards, and playing newly written collaborative material as they go. Each evening is sure to be a unique experience as they all put their many combined years of musicianship and knowledge of song-craft and American music into play for these sessions. The tour will open at Hampton Beach, NH on August 4 and travel South, including stops in Boston (House Of Blues, 8/5), New York City (Beacon Theatre, 8/6), Philadelphia (Electric Factory, 8/7), Charlottesville (Charlottesville Pavilion, 8/9), Cary, NC (Koka Booth Amphitheatre, 8/10), Louisville (Waterfront Park, 8/12) and Nashville (Riverfront Park, 8/13) before concluding at Worlds Fair Park in Knoxville on August 14.
