Brown explained to The Hollywood Reporter
that Grohl had not heard of his Zac Brown Band when they first met. "They just know we've had some songs on country radio," the Nashville frontman said. "And while we've got a great foothold in country music, that doesn't encompass everything we do."
"Dave Grohl's street credit and the energy that was brought into these recording sessions, it's a big deal for us," he added. "I feel like it's kind of the tipping point."
