'audiences like the pedal to the floor!'

Yes, often and perhaps usually. But not all night. What audiences like is variety.

I once made the mistake of going to an all-Mozart concert played on a 'piano' such as he actually played. It had tiny key dip which permits the fingers to fly over the keyboard with little effort. By the end of the evening I was ready to throw something. And I definitely sympathized with the king who said 'Too many notes!'

In other words, it lacked variety.
