Deep in the San Fernando Valley, behind the train tracks, amidst dilapidated warehouses, was rock n' roll's best kept secret. Sound City housed a legendary, one-of-a-kind recording console and became the birth place to the seminal albums that defined 20th century music. Fleetwood Mac, Neil Young, Rick Springfield, Tom Petty, Nirvana, amongst many others, all put magic to tape within these walls. It was Rock n’ Roll hallowed ground. The film tells the story of the studio from its early days in 1969 until its closing in 2011. Famous musicians who recorded at Sound City reunite at Studio 606 – Dave Grohl’s personal studio – for a jam session and to make an album of all-new all-original songs, each one composed and recorded exclusively for the film within its own 24-hour session on that console. Directed by Grohl (Nirvana, Foo Fighters) and featuring interviews and performances by the iconic musicians who made their careers in the studio.
