A cappella music filled the noon hour today on Excursions as two great groups shared songs with us. Eleventh Hour, a high school pop a cappella group from Kettering Fairmont performed first with three covers. Niki chatted it up with the group's current members and about the yearly rotation of voices in the group. After that, Streetcorner Symphony, shared some tunes. They are an all male, professional group based out of Nashville, Tennessee. They just released a new album, Southern Autumn Nostalgia, consisting of all original tunes.
