Last week, Sean Leon introduced himself to The DJBooth with Elephant Graveyard/100 Shots, a two-part cut whose dark, eclectic vibe won it positive reviews on our pages. Premiered yesterday via Noisey, Black Punk Motherfxcker continues in its predecessor’s experimental footsteps, but incorporates a more dissonant, rock-informed edge. J’Vell Boyce, Jordan Evans and Ben Foran‘s instrumental is alternately stark and overwhelming. During Maui Slim’s self-aggrandizing verses, a kick pulses in the back as muffled speech, moaning and what sounds like seagulls drift in and out of the mix. When the hook rolls around, the cut explodes into a squall of guitar noise and pitch-lowered vocals, and the artist ditches the self-assured flows for a punk rock howl. Leon hooks up with Niko Nice to direct the appropiately grimy visuals. This avant-garde banger is the lead single off forthcoming mixtape Black Sheep Nirvana, which is scheduled to drop later this year.
