Zac Brown Band's recently-released EP, 'The Grohl Sessions Vol. 1,' has had fans wondering if there may be more volumes to come.

In an interview with Billboard, band member Clay Cook says that they hope they can record with the Foo Fighters' Dave Grohl again.

"Vol. 1 is literally everything we recorded, but we liked the idea of adding to this at some point," he states. "We don't know what the future holds, but we like the idea, and Dave loves the idea of making more music, too. It's as open-ended to us as it is to you, but Dave was cool with calling it Vol. 1. So maybe Vol. 2 comes in 30 years; we don't know. But we love the idea of the intention to do more, that's for sure."

The EP contains four songs that they recorded with Grohl after meeting him at the 2013 Grammy Awards. The collaboration debuted at No. 5 on the Top Country Albums chart after its release earlier this month.

Grohl also made a live appearance with the band at this year's Country Music Association Awards, playing drums during a performance of 'Day for the Dead,' which appears on the new EP.
