Following the success of Foo Fighters' Sonic Highways series for HBO this past year, Dave Grohl says a second season is not out of the realm of possibility. “There might be a season two,” Grohl told Billboard. “There are a lot of studios.”

While the first season focused on eight U.S. cities and their respective music scenes, Grohl says he's interested in filming an international edition. “If we went to somewhere like Abbey Road it’d be fun to interview someone like Paul McCartney or George Martin, that’d be kind of cool,” Grohl said. “Or go to say, Berlin, and interview someone like David Bowie or Iggy [Pop].”

However, Grohl deferred to drummer Taylor Hawkins as the expert on studios across the pond. “Taylor is the one to ask about the U.K. studios, he’s been to them all, even if they’re kabob shops now,” Grohl said. “He’ll show up and be like, ‘You guys know that they f---ing recorded Queen’s The Game in here, right?'”

Hawkins cited Musicland Studios, a now-defunct studio in Munich, as potential material for Sonic Highways season two. “There used to be one in Munich where Queen recorded a bunch and ELO recorded a bunch, Stones, Zeppelin, it was called Musicland Studios,” Hawkins said.

The Sonic Highways series followed Grohl as he traveled to Chicago, D.C., Nashville, Austin, L.A., New Orleans, Seattle and New York. There, he interviewed aritsts who played a key role in the development of each city’s musical framework. Along the way, the Foos recorded a song at iconic studios in every city, which then appeared in the band’s 2014 album of the same name.

Sonic Highways will be available on DVD on April 7.
