New York City’s Spottiswoode & His Enemies traverse a wide expanse of musical terrain, from straight-ahead rock to gospel hymns to jazz balladry and beyond. Theirs is an evocative, shape-shifting sound that never lingers long on any one style. But don’t call them eclectic. As enigmatic front man Spottiswoode will tell you, “We are expressionists!” Duly noted. Spottiswoode & His Enemies play the Skinny Pancake in Burlington this Friday, May 16.
