"Chicago's the place where I saw my first show," explains Dave Grohl. "The first time I ever saw a live band play was at this little bar called the Cubby Bear right across the street from Wrigley Field. It was just like 'I want to do this for the rest of my life.' So the idea of the song, and the episode, is that once you find that spark and inspiration, that begins your path in life, for whatever it is you want to do."

The Foo Fighters will celebrate the launch of their HBO series, "Sonic Highways", by performing at The Cubby Bear in Chicago and streaming the concert online.

The 8-part HBO series debuts on Friday, October 17 at 11:00 p.m. EST. The program chronicles the making of the band's forthcoming album of the same name, out November 10.
