This week, Sadie Dingfelder leads off the section with a profile of Arthur Harrison—-a Rockville musician and veteran of D.C.’s music scene who is one of the world’s best-known makers of theremins. What’s a theremin, you ask? Well, it sounds like a chorus of moaning ghosts, and you don’t need your hands to play it. Read more!

For this week’s One Track Mind, Benjamin R. Freed chats with The Torches, whose leader happens to also play with Harrison in The Cassettes. Also in music: Geoffrey Himes reviews two forward-thinking, surprisingly conversational jazz records from Bill Frisell and Dave Douglas. Ted Scheinman reviews the latest record from jazz band JJ Grey and Mofro. And Nevin Martell listens to the sophomore effort by druggy U.K. dance-rockers Klaxons.

Elsewhere, film critic Tricia Olszewski reviews two films in which thugs get all Darwinistic, Animal Kingdom and Mesrine: Killer Instinct. And Scheinman reviews Portraits and Persons, an art-historical text that should tell you something about your cat.

In City Lights: Louis Jacobson reviews “Cinecitta Chapel” at Flashpoint. Plus: Cannabis Corpse, “Anacostia: Never Far from Home,” Rupa and the April Fishes, Dr. John, A Gente Luta mas Come, and Kele!
