You’ve probably heard RJ Krohn’s music even if you don’t realize it. The veteran producer otherwise known as RJD2 famously wrote the theme for Mad Men, and “Deadringer” is one of those songs everyone’s heard somewhere, but few could actually name. There’s something both nondescript and timeless about Krohn’s sample-driven instrumental hiphop, which, for whatever reason, has never had the same critical cachet as similar acts like DJ Shadow or the Avalanches. His recent music retains a warm, homespun quality—the man knows how to flip a sample—but he works with vocalists and draws from vintage soul and funk instead of boom-bap beat work. ANDREW GOSPE
