Well, even for a guy packing plenty of surprises, we didn’t see this one coming from Jack White and his Nashville label: Third Man Records announced today that their next 7″ single release will star Detroit rappers Insane Clown Posse, produced by White himself and featuring an adaption of a tune by… Mozart. That’s right: Wolfgang Amadeus Mozart’s 1782 canon “Leck Mich Im Arsch.” As you might imagine, appropriating that title into their new Mozart-inspired verses came naturally for ICP’s Violent J and Shaggy 2 Dope. The A-side, which you can hear below, will hit iTunes and the Third Man store on September 13 along with B-side “Mountain Girl” (a so-called “twangy country song” about meth, moonshine, and shotgun weddings).
