MF DOOM fans, this one’s for you.

For the next upcoming weeks, the masked rapper will release a new song every week courtesy of Adult Swim. The series is called “The Missing Notebook Rhymes” and will feature “all new DOOM jams” and “all sorts of special guests.”

Today, he’s kicking things off with the first track titled “Negus,” which is a collaboration with the late-great Sean Price. The song will also appear on Sean Price’s posthumous album, Imperius Rex, which is set to drop tomorrow, August 8th.
