In our third episode, Alex introduces one of Bach's most beloved church cantatas: "Wachet auf" -- "Wake up!" The watchmen on the tower are calling! At a certain magical moment, Bach removes the bass instruments so we can hear the bright, ringing voices announcing that Christ is coming to the world. Alex also describes the beauty of the rest of the cantata, with audio examples from the Netherlands Bach Society's performance.
