Westside Gunn and Conway, two brothers from Buffalo who make hard-as-fuck ’90s-style New York rap with just the right dose of weirdness, have been two of the leading lights of the rap underground for the past few years. And now they’re headed aboveground. The duo have signed with Eminem, as their Griselda Records label is now under the umbrella of Eminem’s Shady Records. Westside Gunn and Conway are both working on solo albums now, and another album as a duo. And to celebrate their deal, they’ve released a new track called “MachineGun Black,” under their wrestling-referencing Hall N’ Nash group name. Eminem talks on the intro, and the hectic neck-snap beat comes from Just Blaze. Check out the new song below.

As long as Em does not start producing their music, this is great news.
