The Sunday May 12 edition of Jazz Unlimited will present Part Six of the Jazz History of St. Louis: The Black Artists' Group and Human Arts Association (1968-1974). The BAG period in St. Louis is the second time that St. Louis music had an influence nationally. The first time was the Ragtime Era around 1900. When the St. Louis musicians got to New York, they helped change the way jazz and other allied music was played for the next twenty years. We will hear almost all of the recordings made in St. Louis by these experimentalists.
