Chameleon Arts Ensemble resumes its popular Up Close series with a string trio program centered on Bach and featuring violinist Robyn Bollinger, violist Scott Woolweaver and cellist Rafael Popper-Keizer. The Goldberg Variations stands as a pillar of Western music both for its transcendent beauty and for the wonder of Bach’s invention. Hear it anew in an epic string trio arrangement that highlights its striking counterpoint, vast architecture and spiritual depth. Alfred Schnittke pays homage to the master as he too blurs the line between emotion and art with his String Trio, and Mozart used Bach’s Prelude and Fugue, BWV 883 as a model to hone his skills.
