Nikolai Rimsky-Korsakov's Sadko on Youtube

The guy singing Sadko's part can actually play the Russian native instrument 'гусли' which the story from builini describes Sadko as playing, about 10:00 into the second youtube segment:

Magnificent string segment starts about a minute into section 11

Around 9:05 into this segment is Nezhata's description of the big bet in which Sadko pulls the golden fish out of lake Ilmen.

The girl playing Nezhata in this one is beyond wonderful.

Zubin Mehta's father once said Sadko was the most beautiful of all operas and it's one of the four or five most to my own taste.
