Songwriter Clarence Greenwood is a child of the ’70s and the South, and the country folk tunes he turns out under the name Citizen Cope are deeply rooted in his own experiences. In the vein of classic singers like Neil Young and Willie Nelson, Citizen Cope combines soulful vocals and simple, evocative melodies on unforgettable self-released albums acclaimed for their emotional resonance. This weekend, Citizen Cope strips down his sound for two acoustic nights, with meet-and-greet packages available. A portion of each ticket goes toward art programs for middle school students living on the Northern Cheyenne Reservation in Lame Deer, Mont. Feb. 13–14, at City Winery Napa, 1030 Main St., Napa. 8pm. $46–$66. 707.260.1600.
