General Motors Concerts, offering classical music on the radio, were heard in different formats on the NBC Red and NBC Blue networks between 1929 and 1937. The concerts began 1929-31 as a 30-minute series on the Red Network with Frank Black as the musical conductor on Mondays at 9:30pm. It also aired as General Motors Family Party.
