SALT LAKE CITY – Ballet West’s “Swan Lake” promises enchantment, mesmerizing movement and a love story that transports audiences from the bleakness of winter. “There’s something so powerful about seeing that the symmetry and the clean core work that it’s mesmerizing, and I think that’s why so many people love it because it’s almost hard to put your finger on what’s so mesmerizing about it. It’s a combination of the music and then also just the fact that you’re seeing 18 soloist ballerinas on the stage at the same time and the strength of that, visually, is very unique to ‘Swan Lake,'” said Emily Adams, who dances the lead role of Odette, the princess who gets transformed into a swan.
