MF Doom - Checkmate ft. Earthquake

"Checkmate" is an unreleased MF Doom track from 1994 that found its way online in 2012 thanks to the Dirty Waters blog. As you can see, the song also features an MC by the name of Earthquake (also formatted as Earth Quake sometimes). Not much is known about Earthquake except that he also appears on the classic KMD song "Stop Smokin' That Shit" off Black Bastards, and that he's from Freeport, or at least that's what Doom told author Brian Coleman during an interview for his book, Check the Technique Volume 2: More Liner Notes for Hip-Hop Junkies. Regardless, the song depicts Daniel Dumile at an interesting phase of his career, before he'd made the transition from Zev Luv X to Doom (hear how he refers to himself several times here) but after Subroc's death and the final Black Bastards recordings. In that regard, it's one of a kind.
