Leontyne Price and Marilyn Horne singing a duet from Rinaldo. I'm stunned at the beauty of Price's high notes. They both are about the same height, which means not very tall. Which makes the volume Price can produce even more impressive. Although there have been quite a few "short" blasters.
This is one of those beautiful Händel duets which overlaps so cleverly.

It works very well in a faster tempo and becomes thrilling.
