It is hard these days to find truly talented dancers, who also find dances worthy of their talent. The great thing about the recent surge of ballroom dancing, along with shows like Dancing with the Stars, is that they're reviving this tradition, and also giving great dance repertoires to aspiring dancers.
Derek Hough (of Dancing with the Stars fame) is one young dancer who, for now, is keeping this tradition alive.
The video above is not great quality, but it is his style and grace is clear.
One thing, though. They really have to work on the music. I think it affects the rhythm, and the beat, and where the dancers put the accents, which spoils the flow of the waltz. I've written about this before.
