Representing Brooklyn and the outer Bronx, DJ Premier and Pete Rock sit at the foundation of quintessential New York hip-hop. Masters of digging for dusty grooves, both came up in the early 1990s as producers for duos that rode funk-jazz loops and bedrock-solid breaks. They continued chopping up samples and laying down concrete percussion as celebrated solo artists. Premier is slightly more minimalist, Rock more melodic; both aim aggressively for the gut, and together they go down smooth as gin and tonic, rum and Coke, a whiskey sour. They're set up in a head-to-head scrimmage at Mighty in a sequel to September 2011's legendary smackdown, and beat junkies can expect them to pull decades of club bangers, funk-soul stabs, and adrenalized scratches out of their proverbial milk crates.
