We have a "Folklife Festival" here in Seattle (our Memorial Day weekend, end of May) that features a lot of, um, ethnic music, dance and art. The goodwife and I have been regular attendees, volunteers and performers (Highland pipes, Celtic harp, and songs in Scots Gaelic) since 1983, and wouldn't miss the event for the world.
All this by way of saying we've seen and heard some pretty neat stuff from all over over the years, and the Oriental (Korean, memory says) fan dances are among them. Amazing.
