This week, we're talking with Mark Grizzard, from the Peoria Area Civic Chorale, about their spring concert, "Music of Our Homeland." The program draws from range of American musical traditions -- folks songs, gospel, bluegrass and contemporary pop. Grizzard talks about some of the individual pieces, and about what ties them together. Performances are Saturday night at 7:30, and Sunday afternoon at 2:30, at First Federated Church in Peoria.
