During a Captain Murphy/Flying Lotus (the same guy, in case you forgot) show last night, the Brainfeeder maestro premiered something that should make any rap fan's hair stand on end.

A new cut during the performance featured verses from Earl Sweatshirt, who appeared on Captain Murphy's Duality mixtape, and the legendary MF Doom. A fan-shot of the cut is available below, which is, unfortunately, the only info we have as of now on the song.
