The band recorded one song at each stop with local legends sitting in (for example, members of Cheap Trick are said to be featured during the Chicago portion, according to a source) while the lyrics were written "in an unprecedented experimental style," reads a statement detailing the project. "Dave held off on putting down words until the last day of each session, so as to be inspired by the experiences, interviews and personalities that became part of the process."
The series, which Worldwide Pants is executive producing, comes on the heels of Grohl's directorial debut, the 2013 Grammy-winning doc "Sound City," which told the story of the Van Nuys, Calif. studio where Nirvana recorded the seminal album "Nevermind" and featured interviews with such iconic artists as Paul McCartney, Stevie Nicks, Neil Young and Trent Reznor, among others. Similarly, the HBO series will, in Grohl's words, present "a love letter to the history of American music" with each episode exploring the cultural impact of these artists' hometowns.
The HBO series is produced in conjunction with James A. Rota, John Ramsay and Therapy studios, and written by Mark Monroe and Grohl for Roswell Films, a division of the Roswell Records label that releases Foo Fighters' music.
An official release date for the Foos' forthcoming eighth album has yet to be announced.
