At this point, you're either really excited about the upcoming Foo Fighters documentary series, 'Sonic Highways,' or you're tired of hearing about it. After watching this video, though, we think you'll fall into the first group.

We've known for some time that the Foos were going to travel to different legendary studios across America, documenting the history and importance of each one -- and then they'd write and record a song there. In this video interview with Dave Grohl and the rest of the guys (watch it above), we learn more details about what they'll be doing, including the Foo frontman's process for writing lyrics for each song.

Grohl interviews musicians native to each city they visit, then uses that interview as a launch pad for the words for the song the Foo Fighters write and record there.

The other members of the Foo Fighters also discuss what they each got out of the experience. Guitarist Pat Smear talked about how he came to love the places they visit.

"I really liked falling in love with cities that I actively disliked before. I never leave my hotel on tour," Smear said. "I never even open my curtains. But I'm not gonna be like that, at least with a few cities."

The Foo Fighters will release their first single from the series and album, 'Something From Nothing,' this Thursday, Oct. 16. Oh, and all this week, they'll be performing every night on 'Letterman.' And 'Sonic Highways' premieres on HBO Friday, Oct. 17 -- the album (same name) hits store shelves Nov. 10 via RCA Records.
