Earlier this week, Foo Fighters launched a countdown on their website that got fans’ wheels turning as to what might happen when the clock runs out on Nov. 23. There’s still no confirmation as to what that day will bring, but Butch Vig -- the producer behind Sonic Highways, Nirvana’s Nevermind and countless others from the Smashing Pumpkins, Sonic Youth and more -- told Billboard the band is in talks for a second installment of Sonic Highways.

Vig appeared on the latest episode of Billboard’s Alt in Our Stars podcast -- which you can hear in full at the bottom of the page -- and he told host Chris Payne the follow-up to Sonic Highways and the second season of the corresponding HBO series could arrive next summer.

“I think there is going to be a Sonic Highways II,” Vig said. “But it’s still in discussions right now. I know Dave [Grohl] and HBO both really want to do it, but it’s going to be different. It’s not going to be the same exact format as the last album… if it happens, it’ll probably happen next summer.”

Vig also discussed his work as the drummer for Garbage. The band recently celebrated the 20th anniversary of their self-titled debut, and according to Vig, they're currently working on a new album. (The band first teased their sixth LP a year ago.)

“We are 90 percent finished with a new album,” he said. “[We’re] recording in December and we’re gonna mix it in January and, fingers crossed, it’ll come out around May 1.”

When that album arrives, it will follow 2012’s Not Your Kind of People.
