Do you mean it was “WOW” compared to other performances of Messiah you have heard before from this group, or compared to other performances of Messiah you have heard anywhere by anybody? Or do you mean you never heard Messiah performed live before and were blown away?
Handel said that as he was writing Messiah that he felt as if the heavens had opened and he could almost see God. He felt profoundly inspired. I think he was right.
Don’t read so much into it. I just meant, “WOW”!
