Zac Brown Band, 'The Grohl Sessions, Vol. 1' (2013)
"They're unbelievable," Dave Grohl said of the Zac Brown Band in a 2013 interview with Rolling Stone. After joining the group for a performance at the CMA Awards, Grohl ended up producing and drumming on the group's 2013 EP The Grohl Sessions, Vol. 1. "People are like 'oh, it's country.' 'No, it's not, it's like the Allman Brothers.' 'No, it's not, it's jam band.' I don't even know what you would call it, it's fucking great."
