The troupe combines classical ballet and Chinese folk style in its colorful productions known for spectacular sets and costumes.

Expect high levels of technical skill from this company trained in the traditions of Russian ballet. A free pre-performance discussion will be held at Solera at 6:15 p.m. (7:30 p.m. Tue. $42-$70.
