The Escher String Quartet is at the forefront of American string quartet playing for their mix of profound musical insight and rare tonal beauty. The group’s M.C. Escher-inspired philosophy of balancing individual components with a cohesive whole comes to life in an evening of Classical and 20th Century Quartets. Haydn’s “Lark” soars with appealing melodies and fluttering figures; Janáček’s String Quartet No. 2 conjures the intimate side of string playing; and Ravel’s glorious Quartet in F major traverses the full range of human emotion from introspection to exuberance.
