Editors’ Notes Zac Brown and company have made a career out of being unpredictable, but they twist the eclecticism knob all the way up here. It’s hard to think of another album that contains bone-crunching hard rock (“Heavy Is the Head,” featuring Soundgarden’s Chris Cornell), ukulele-driven reggae (“Castaway”), brassy swing-jazz (“Mango Tree”), and big, bold, club-ready dance tracks (“Beautiful Drug”) all under one roof. But most impressive of all is that Brown and his band sound completely natural throughout.
