The drum & bass veteran talks about bass music eras, dance culture in America and his new album, Contact. British artist Nicolaas Douwma, AKA Sub Focus, has been steadily putting out big-room drum & bass since the early 2000s. In more recent years, he's become staggeringly popular, releasing a string of Top 40 UK pop hits that have made him synonymous with a more mainstream sound. His influence looms large across a whole generation of young producers, particularly in the US. In this Exchange, Douwma sits down with Resident Advisor editor Gabe Szatan at the beautiful Red Rocks Amphitheater in Colorado. They speak about how he hit number one in the US dance music charts last year, as well as how drum & bass moved from being popular with a "secret clique of people" to becoming what, for lack of a better term, could be called "brostep." There's a new Sub Focus album dropping on November 21st called Contact, which includes collaborations with Grimes and Katy B. Grab your copy when it comes out.
