Post performance euphoria is a crazy sensation. The closest description would be a “butterfly effect” as time begins to move back to normal.
Performing slows time as focus becomes concentrated, listening and observing every micro-movement of the group and conductor. Remnants last for hours and it takes a toll on the body.
The performance was sensational. The soloists played the tango from True Lies as an encore (cause they can). Wow.
Beethoven was good, actually!
