Foo Fighters frontman hadn't heard ZBB before working with them
"It's amazing," Grohl said. "It just sounds like Zac Brown."
As previously reported, Brown had always wanted to work with Grohl, but the Foo Fighters frontman said he didn't know the country/folk band's music.
"I never heard him before I went to record him. Like the first time I ever heard him was when I hit record," Grohl said with a grin.
Grohl has apparently learned a lot since then as he recently performed with ZBB at the CMAs.
