Lead singer Zac Brown enlisted a talented group of his musical friends and heroes for the reimagined versions, of previous released tracks, that comprise The Comeback(Deluxe). Their latest “audio-nirvana collaboration” (MusicRow) features 3x GRAMMY nominee Ingrid Andress on “Any Day Now,” where “her piercing soprano underlines the chorus message of regret…and the result is gorgeously melodic dynamite” (MusicRow). Multi-platinum-selling artist Cody Johnson joined the band on “Wild Palomino,” called a “standout because of the added emotional depth bolstered by Johnson's distinctive vocal delivery” by Taste of Country. Whiskey Riff applauds how Jamey Johnson’s vocals make “[‘Stubborn Pride (with Marcus King)’] that much more powerful. We’re talking about one of the best voices in all of mainstream country music, one of the best songwriters in country music history in Jamey Johnson, and the incredibly talented Marcus King joining forces for beautiful harmonies, and unique transitions in vocals between the three artists.” Iconic singer/songwriter James Taylor lends his musicianship to “Love and Sunsets” while their current Top 15 radio single “Out in the Middle” gets new life with the addition of country superstar Blake Shelton for a “foot-stomping anthem…[where] vocals fromZBBfrontman Zac Brown blend seamlessly with Shelton’s signature pipes” (Country Now).
