Rolling Stones Mobile Studio

The Rolling Stones Mobile Studio was a mobile recording studio owned by the English rock band The Rolling Stones. Numerous bands and artists have recorded music using it, including Dire Straits, Deep Purple, Lou Reed, Bob Marley, Horslips, Fleetwood Mac, Bad Company, Status Quo, Led Zeppelin, Iron Maiden, Wishbone Ash and the Rolling Stones themselves. More recently, the unit has been acquired by a museum in Calgary.

The concept for The Rolling Stones Mobile Studio first came about in 1968 when the Rolling Stones decided they needed a new environment in which to record music. Tired of the 9-to-5 limitations of a regular studio, the Stones decided to use Mick Jagger's new country house (Stargroves) in England to record new music. All the necessary equipment had to be brought to the house, so the idea of putting a control room into a van was brought up by their road manager and pianist Ian Stewart.

Under Stewart's guidance, a variety of top engineers and producers, including Glyn Johns, were consulted in the project's creation, which was then taken to Dick Swettenham's company Helios Electronics. Known for making mixing consoles for some of the most exclusive studios of the time, the company then produced the first working version of The Rolling Stones Mobile Studio. Originally only intended for use by The Stones, the unit soon gained popularity among the likes of other classic rock bands, such as The Who, The Faces, and Led Zeppelin.
