"On one of my mixtapes, “Deevil,” I had a song called “13.” I was working out a three album story that I was trying to tell. Mike was really liking the idea so we thought about making it a dual idea rather than just my idea. So we reworked it. First thing it’s got to do with everything All 6s and 7s, if you’re familiar with what that term means. So we just added them together. I got this old movie poster from the 1960s that says ''When The Clock Strikes 13'' and I started a real interesting take on time and how time moves. We picked 13 because it was conducive to 6s and 7s and being in a place of disarray, or coming out of a place of confusion -- being all 6s and 7s. And if you throw them together, since there’s two of us, then it’s ''13''. It’s weird, man. We’re some fucking Rap nerds, I’m trying to tell you. It’s too much fun to fuck with it and layer it up."
