The graceful extension of a prima ballerina. The gasp-worthy leaps or a series of dizzying twirls by an entire company. Everyone remembers a stunning night at the ballet, and Gwinnett Ballet Theatre celebrates those famous dances that have delighted audiences for decades. Performed by GBT's dancers, you'll be treated to such numbers as "Swan Lake Act 2" and "Pas de Quatre." For even more contemporary dance fireworks, friends of GBT like the Los Angeles-based company The Assembly and Portugal's Kayzer Ballet will also take the stage to showcase exciting new choreography. It all goes down at Duluth's Infinite Energy Theatre.
