Describing the album's direction, Zac told Rolling Stone earlier this year that it will have "things that people will expect and things that they don't." "Homegrown" the band's highest chart debut, which is bulleted at #10 on country radio this week has earned massive fan support and early praise for its "rock feel" (Country Weekly) and "intricately arranged vocal harmonies" (Billboard); "Dress Blues", written by Jason Isbell, is a somber and stirring tribute to members of the military who have been killed in service; and "Heavy Is the Head", which features Chris Cornell, the multi Grammy winning singer/songwriter and legendary front man for pioneering rock bands Soundgarden, Audioslave and Temple of the Dog, makes its world premiere this Friday, March 6th on iHeartRadio's Mainstream and Active Rock station. The album also features a collaboration with Sara Bareilles.
