Elgar, while Studio Two would be hosting sessions with the Rolling Stones. Robertson Grant successfully innovated a completely floating space weighing seventeen tons, supported by rubber pads. The décor and furnishing of the new studio Two was designed by Mick Jagger. Later on, Grant added probably the first instant acoustic change, using rough sawn wooden slats which could cover or reveal sound-absorbing panels behind them and change the acoustic sound. This made the room suitable for the recording of both rock and orchestral music, at the pull of a cord. By the turn of the 1970s, many orchestral works and film scores, such as the original album version of the rock musical Jesus Christ Superstar, were also being recorded at Olympic. The studio produced film music for The Prime of Miss Jean Brodie (1968), The Italian Job (1969), the movie version of Jesus Christ Superstar (1973), The Rocky Horror Picture Show (recorded in studio Two in 1975) and Life of Brian (1979), amongst others. Olympic Studios' sound mixing desks were a creation of the maintenance staff and built specially for the studios.

Swettenham later started to manufacture the consoles commercially as Helios desks. The first desk of this type was commissioned by Grant as Helios One for studio Two. Olympic desks and their Helios spin-offs are still highly regarded and sought-after for their sonic qualities today. Virgin Music era For many years, copyright problems with the use of the word "Olympic" prevented the history of the studio from being more widely promoted, which became an important factor in its arch-rival Abbey Road Studios attracting greater recognition, due to promotion by EMI. In 1987, Virgin Music bought the studios and the property was refitted to a different practical and acoustic specification, further to consulting with Sam Toyoshima, a Japanese studio builder, who surprisingly declared the studio "unfit to record music in". Barbara Jefferies, then Studio manager for Virgin Music at Olympic Studios, instructed that the master tapes of the studio's vast library of recording sessions be discarded. The disposal of these tapes was unsecured. They were put into skips outside the building, remaining there for days. Some were recovered by people unnassociated with the studio, and ended up as highly sought-after bootlegs. The re-vamped studio continued to attract
