"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.
