Several months ago it was revealed that Slipknot / Stone Sour vocalist Corey Taylor was one of the artists recording music with Foo Fighters frontman / ex-Nirvana drummer Dave Grohl for the latter's ;Sound City' documentary. Now Taylor has revealed more about the collaboration in an interview with Phoenix radio station KUPD (watch below).

Taylor reveals, "[Dave Grohl] sent an email to me, basically explaining this huge project he was doing – the documentary around the infamous board that he got from Sound City, which so many people have recorded on – myself included – we did 'Iowa' on that board…He bought it, and I loved the idea that he was like 'how many albums have been made on this board?"

He adds, "He wrote the song, he sent me a demo of it and I was like 'this is fantastic' and I just basically wrote the first thing that came off the top of my head. He didn't even hear it until I went down there to record it. And I laid it down and he was just like 'wow.' Because we did it old school – two inch tape, take after take after take. And with that board, man. It just sings, it was really, really cool."

Countless legendary albums were recorded at Sound City, including Nirvana's 'Nevermind,' Fleetwood Mac's 'Rumours,' Neil Young's 'After The Gold Rush,' Tom Petty And The Heartbreakers' 'Damn the Torpedoes' and Rage Against the Machine's self-titled debut.

While an official release date for the documentary has still not been revealed, the web site for the film has several video clips and other info.
