With incredible physicality, razor-sharp precision, and boldly inventive choreography, the Australian performance troupe Circa takes the concept of "embodying" a work of music to an electrifying extreme in its production Opus. The instrumentalists of the Debussy String Quartet join the ranks of the troupe's balletic acrobats as cast members, performing three Shostakovich string quartets as their nimble cohorts create a counterpoint in motion to the emotionally tumultuous music—springing, snapping, flying, twirling, and stacking themselves in masterful feats of balance and strength. "Opus is cut-glass, caviar circus. It's black tie and ballgown circus ... graceful, bombastic, profound" (The Telegraph, London).
