The Dutch duo of Sunnery James & Ryan Marciano have developed a style of house music that is truly all their own. Together with Chocolate Puma, they have produced a new track, "Stiffness," that encompasses their uniquely tribal style of house music. The track is set to be released June 10th on Steve Angello's record label, X. This track weaves together beautiful percussion that has dance floors bouncing. Here is a preview of "Stiffness" to get you hyped for the release.
