MisterMack is a young producer living in College Park in Maryland, but he’s making music that’s a bit different from most youngsters finding their sound. It’s mature, sampling throwback records and creating his own. The one we’re highlighting is a club remix of Usher‘s “Climax,” but we’re also going to suggest that you check out his Infatuation/Heartbreak EP while you’re at it. It’s that thin line between R&B and electronic that we absolutely love, and it’s available for free download right here. The Usher flip is fresh, and freshly downloadable directly below. Free gems from a promising 20-year-old producer is never a bad thing. Have at it.
