Walter Martin’s second album after the dissolution of the stormy, passionate Walkmen explores his love for art history. While that may not seem like a subject to sell a song on, the subject matter is transformed by Martin’s warm, restless sense of humor, which discourses on subjects ranging from the tipping habits of college kids (“Jobs I Had Before I Got Rich and Famous”) to 19th-century paintings of boys with pet squirrels (“Watson and the Shark”). A folksy, deceptively simple album, Arts & Leisure puts high culture on a low shelf and makes the mundane glow.
