Gang of Four today premiered a brand-new song and a brand-new lineup, with vocalist John “Gaoler” taking the place of founding member Jon King, who had participated in the group’s mid-2000s reunion and 2011 studio album Content.

Gang of Four this week announced it will release ‘Content’ — its first all-new studio album in more than 15 years — early next year on CD, vinyl and as part of an ‘Ultimate Content Can’ that includes lyrics, artwork, a scratch-and-sniff booklet and ‘vials of band members’ blood.’
