What started as a news site about Australia's dance-music scene has grown to become an exhaustive authority on the global dance industry. Part webzine, part database, and part online community, the site offers up information ranging from news and reviews to event listings to artist profiles to club directories, in addition to accoutrements like ticket sales, films, and podcasts. RA has doubled its traffic in the past three years, averaging more than two million users, and shows no signs of slowing, with Clement and Sabine unveiling a major redesign in January, expanding the site's reach and interactivity. Beyond the web, the RA name has been attached to club nights, festival collaborations, and other events around the world. The site ultimately remains more influential overseas than in the U.S., but as dance music scenes and subgenres like deep house continue to take off with American audiences, RA is poised to become the top media brand for electronic music.
