West Coast spitter Captain Murphy, whose identity remains a mystery, returns today with a new joint off his upcoming Duality mixtape. It's the Flying Lotus-produced "The Killing Joke," which features dark/braggadocious rhymes and a slew of samples from The Dark Knight. Those samples are what help shape the narrative of the track, which you can stream below.
