The subject of this week's program is A Cappella Holiday Music with Mike Maino. Mike has a chance to do the first in a series about great American a cappella groups. In this case, the artists are a group from Florida, “The Liberty Voices,” along with “Acoustix” from Dallas, and “Rockapella,” which has Rhode Island roots.
