Dave Grohl is making the talk show rounds this week, hitting up 'The Colbert Report' and 'The Late Show With David Letterman' to discuss and promote his 'Sound City' documentary. After an appearance on 'Colbert' earlier this week, last night (Feb. 14) was Letterman's turn.

During his interview with Letterman, Grohl recalled his first experience with the Sound City studio in Los Angeles, recording Nirvana's 'Nevermind' album there in 1991. He explained, "We booked into that studio cause it was cheap. It was $600 a day and they were sort of kind of past their prime and their heyday. In '73, they were state of the art, brown shag carpet on the walls was cool, but by 1991 it was not. So we walked in and it was a dump. It looked like a burned out Chi-Chi's."

However, Grohl said the sound of the studio was undeniable and they got the "big" feel they were hoping for when recording the classic 'Smells Like Teen Spirit.' He adds, "The 16 days we were there changed my life forever. "

In addition, Nirvana drummer-turned-Foo Fighters frontman added a performance to his 'Letterman' appearance, bringing out his 'Sound City Players' with Fleetwood Mac's Stevie Nicks on vocals for 'You Can't Fix This' from the film's soundtrack. Nicks has a history with the Sound City studios as well, first meeting Mick Fleetwood there prior to she and Lindsey Buckingham joining the band. The group also recorded some of their finest music at the studio.
