On Thursday, July 19, acoustic guitarist Dan Stevens will bring his American roots style of music to the Essex waterfront when he performs at the Connecticut River Museum's Thursdays at the Docks program. Back for a fifth summer season, Thursdays at the Dock extends the museum's hours by opening the first floor galleries, museum shop, and north deck from 5:30 to 7:30 p.m. every Thursday through Aug. 30. All are invited to sample the Connecticut River's great heritage and natural beauty while enjoying music and refreshments on the waterfront. Each week, featured area musicians perform a diverse mix of maritime folk, bluegrass, folk rock, and other popular styles. Stevens, called "Connecticut's hardest working bluesman" by the New York Times, is an Old Lyme resident who tours continuously along the East Coast, the U.S. Virgin Islands, and Europe. Admission is $5 per person; museum members are admitted free. Cash bar and light snacks are available.
