Details: 2017 release from the a cappella group. The group competed in and won the fourth season of The Sing-Off on NBC in 2013. In terms of musical roles, Home Free is structured like a traditional barbershop quartet, with a lead tenor, two harmony voices, and a bass. The lead tenor, who fronts the group and sings most of the solos, is Austin Brown. Tenor harmony is sung by Rob Lundquist, baritone harmony is sung by Adam Chance, and Tim Foust sings bass. In addition to the four voices, percussion sounds are provided by beatboxer Adam Rupp. Although Brown is Home Free's primary soloist, all of the other members occasionally sing solos as well.
