British producer Dan Carey, aka Mr. Dan, has long stirred the pot behind the scenes with some delicious offerings on many of the UK’s freshest labels, most recently as part of the band Sexwitch with Natasha Khan and TOY. Today, he shares “Firewater,” an unlikely one-off collaboration with Detroit veteran and frequent Dilla collaborator Guilty Simpson. Carey’s beat is a murky, sinister jaunt layered thick with warped synths and dense drums. Seemingly, there is little room for any vocal to cut through the swampy low-end depths — the beat could easily be satisfying as an instrumental. But Carey reached out to Simpson and Simpson only, and his velvety voice takes the track to another level. Surrounded by the heavy, synthed-out beat, Simpson spits some vivid rhymes with dissociate storytelling and gritty Detroit-centric brags. This collab was a long shot coming to fruition; Carey recalls that when he reached out to Simpson, “There was no way I thought I’d get a reply.” But he did, and it turned out oh so dope. Listen below.

“Firewater” is out 2/26 on Speedy Wunderground. Pre-order is available here.
