For encores, they would play Russian folk compositions. There's nothing like a full mandolin orchestra playing throbbing/passionate or merry/lively Russian folk music to make your toes tingle and your heart soar. These encores always brought standing ovations.
A classical mandolin orchestra is a thing of beauty to the ears.
I don't know if there are any more such orchestras. Milwaukee used to have one, I believe.

Mandolins (at least the bluegrass kind, not sure about Russian) are great for playing violin/viola/cello because the positions are the same.
I have a friend who plays (or at least used to play) for the Denver Mandolin Society. Thanks for the ping.
