The official YouTube channel of "Sound City", the new feature-length documentary directed and produced by FOO FIGHTERS frontman Dave Grohl, has been updated with a short clip of RATT members Stephen Pearcy (vocals) and Warren DeMartini (guitar) talking about their musical memories. Check it out below.

"Sound City", about the legendary and now defunct recording studio in Van Nuys, California, was conceived by Grohl after he bought an equally famous Neve 8028 recording console from the studio. The console, built in 1972, is considered by many to be the crown jewel of analog recording equipment, having recorded classic albums by artists such as NIRVANA, Neil Young, FLEETWOOD MAC, Tom Petty, CHEAP TRICK, GUNS N' ROSES, RAGE AGAINST THE MACHINE, SLIPKNOT, NINE INCH NAILS, METALLICA and countless others over the past 40 years.

Producer Butch Vig, who is working on the movie's soundtrack with Grohl, told The Pulse Of Radio how the seed for the film was planted. "When Dave got the board and put it in his studio, he had the idea to interview people who had recorded there. And he got a roster list of all the bands that had recorded there over 20 years — it's huge. I mean, it's like, FLEETWOOD MAC and THE JACKSONS and Tom Petty and METALLICA... I mean, it's amazing. And so Dave started calling up people and saying, 'Hey, man, do you want to do the interview for this documentary?' And everybody said yes."

Grohl said in a statement about the project, "'Sound City' is a film about America's greatest unsung recording studio . . . it was the birthplace of legend. It was witness to history. It was home to a special few, intent on preserving an ideal. An analog church, a time capsule, the last bastion of a craft defied by technology. It was rock and roll hallowed ground."

Grohl interviewed dozens of artists and producers who worked at Sound City about their experiences there and some of the legendary albums that came out of the studio.

The film will also feature brand new performances by artists who recorded at Sound City, including collaborations between musicians like SLIPKNOT's Corey Taylor and Rick Springfield.

Grohl hopes to get the film, his first feature-length project as a director, out by early 2013.
