Transa is a British EDM production unit, composed of the brothers Dave and Brendan Webster. They have produced mostly trance music over their career, but have slipped into the realm of progressive house on occasion. They have also recorded under the aliases Cascade and Catcher.

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, Tiësto, Ferry Corsten, Venga Boys, Armin Van Buuren, Blue Amazon and Alice Deejay.
