For decades, the concept of pop music was synonymous with Trident Studios, the pioneering facility in the heart of London's Soho district. Their client list reads like a who's who of pop: The Beatles, Elton John, David Bowie, the Bee Gees, Genesis, Frank Zappa, Joe Cocker, Kiss, Lou Reed, Peter Gabriel, Marc Almond, Soft Cell, Queen, the Rolling Stones, Thin Lizzy, Tina Turner, T-Rex, and Yes. At the heart of the studio's sound was the Trident A Range console. It became so well known for its gorgeous, musical EQ and the full, rich tone it imparted soon, studios around the world were placing orders for an A Range of their own. Although only 13 were ever made, they created a legacy that continues to this day.
