This week"s Billboard cover story, on stands Monday features the UK dance duo Disclosure, consisting of brothers Howard and Guy Lawrence.

In their first major magazine cover feature, the brothers talk with Billboard about bringing "class and soul" into EDM, thinking Sam Smith (who is featured on their hit "Latch") was a woman, and not being recognized in public (just yet).

Howard says Disclosure aims to bring depth to dance music.“We’re trying to bring class and soul into the songwriting ... using jazz chords that have emotion instead of boring, stabby EDM triads,” he says. “You can play ‘Latch’ in a massive nightclub or cover it in a jazz ensemble.”

Though they’re flourishing stars, the pair don’t have to worry about being mobbed by fans or paps just yet. “No one recognizes us unless we’re together,” says Guy.

Before meeting Smith, whose gorgeous falsetto gets up into range most male vocalists can’t reach; the Lawrences thought that Sam was a lady. “We were amazed he wasn’t a girl,” says Guy of hearing Smith for the first time.
