MF DOOM keeps his Missing Notebook Rhymes series rolling by dropping off a new collab with Kool Keith called "Notebook 04." Listen to the Astronote-produced record below.

Keith and DOOM, two of rap's resident oddballs, have a history of dope collabs, including the recent "Super Hero" and the Viktor Vaughn cut "Doper Skiller."

"Notebook 04" is the latest entry in DOOM's current 15-week run of releasing new records, following collabs with Jay Electronica and Sean Price.

DOOM's always been a mysterious guy, but Adult Swim managed to secure 15 unreleased tracks for the Missing Notebook Rhymes series. When we spoke to Jason DeMarco, senior vice president and creative director for Adult Swim, he said he was able to pull it off because he's been friends with the masked villain since Adult Swim funded the Danger Doom album over 10 years ago.
