This is something called Watchathon week on cable here, where they give free access to various channels. One was a classical music channel and I listened to two Ascension Oratorios, one by CPE Bach and one by his father JS Bach.
CPE was first and was wonderful, a joyful musical experience. But when the first phrases of the JS rang out, you knew you knew you were listening to something more. I tried to classify the difference, since the instruments and singers were all the same. It's like JS gives you access to another musical plane, that few others have access to. He opens a door that others have no key to. You have musically ascended.
