Alchemist just dropped a maxi-single in collaboration with SSUR, featuring three tracks and a ton of rappers: “Camp Registration” enlists Evidence (as 1/2 of Step Brothers with Alchemist), Action Bronson, Blu, and Domo Genesis over a pitched-up soul sample; “1010” is a spaced-out, heavy-hitting cut featuring guest appearances from Domo Genesis, Action Bronson, Meyhem Lauren, Roc Marciano, and Despot; and “Tesla” features the likes of Domo Genesis, Freddie Gibbs, and Hodgy Beats over a blaring brass section. Stream and purchase “Camp Registration”, “1010”, and “Tesla” below.
