Transa is an EDM production/DJ unit composed of brothers Dave and Brenden Webster, also known as Cascade. Based in Great Britain, they have produced mostly trance music over their career, but have slipped into the realm of progressive house on occasion. Several of their songs and remixes have appeared on mix albums over the years, most notably Paul Oakenfold's first album in the Tranceport series and X-Cabs's Exposure 1. They have remixed for BT, Art of Trance, and Tiesto, and even released their own mix album in Exposure 3, although that release is widely regarded as the worst in the series.
