Right now, the beloved underground rap supervillain DOOM is in the process of releasing a new song every week, via Adult Swim’s The Missing Notebook Rhymes series. Today, he follows up last week’s “Notebook 03” with a new song called “Notebook 04.” And on this one, he teams up with Kool Keith, a fellow veteran underground rap absurdist who’s had a whole lot of fun inventing characters. The two last teamed up on Keith’s “Super Hero” last year, and you can hear them join forces again below.
