A choir I sing with is doing a song which I believe has some sort of connection to Volyn. The Shostakovich piece is called Венули Ветры - V'enul'i v'etry which I think means "Blew the Winds"
Here's a YouTube recording from a choral festival in Moscow:http://www.youtube.com/watch?v=woWM_MDxyzA
When I questioned our director about the song, he responded
"I was researching a bit about the Volyn province. There is obviously no sea there, but one interesting large lake -- Lake Svityaz. Maybe this body of water became a sea in folklore (it's very large -- apparently one can't see the other side...)"
I would love to know if the song (please listen to it on youtube at http://www.youtube.com/watch?v=woWM_MDxyzA
and see if you think it has any connections to Volyn.
