Johann Sebastian Bach composed a great deal of sacred music and these works were to lead the congregation into the spirit of the church year. Advent is the time before Christmas and Bach took six cantatas from the holiday celebrations and combined them into his Christmas Oratorio. This Sunday KPAC broadcasts the fourth part of this work, featuring a new recording with Riccardo Chailly and the Gewandhaus Orchestra. This cantata deals with the birth of Jesus and his naming ceremony. Join Ron Moore this Sunday afternoon at 2 for this spirited performance of this Holiday classic on KPAC & KTXI.
