Vienna, Virginia's Luke Mitchem is a sensitive folk singer-songwriter in the traditional troubadour tradition – like a softer Bob Dylan you might say, or a more melancholic Pete Seeger. He performs with a four-piece band featuring mandolins, acoustic guitars and harmonica, plus supporting vocals from Stacie Fredrich. He’ll open for critically acclaimed fellow troubadour David Dondero. Wednesday, Sept. 2, at 8 p.m. Jammin’ Java, 227 Maple Ave. E. Vienna. Tickets are $10. Call 703-255-3747 or click here.
