Grohl addressed the Television Critics Association at an event in Beverly Hills last week (July 10) to reveal what will go into his eight-part series titled Foo Fighters: Sonic Highways, airing on HBO starting in October.

"Music can seem a little one dimensional… but when you get a little deeper into the artist or the song, it creates this emotional connection," Deadline reports Grohl said.

The series will explore multiple American cities, including Chicago, Nashville and Austin. In each Grohl will interview a local musician and record a song in a local studio. Rolling Stone reports that he referred to it as "a love letter to the history of American music."
