The Grohl Sessions, Vol. 1 (EP)
Released: May 2014
Label: Southern Ground Artists
This four-song EP was produced by The Foo Fighters' Dave Grohl, who does a great job igniting the Zac Brown Band's sound, turning the country yacht-rockers into a more energized country-rock band. Their signature harmonies -- lusciously laid out on the soulful "All Alright" and the lilting "Let It Rain" -- are still beautifully intact, though. Grohl gets behind the drum kit on "Day for the Dead," which the band debuted at the 2013 CMA Awards, expertly propelling the song into tasty Southern-styled jam rock territory.
