The Knights, an orchestral collective led by an open-minded spirit of camaraderie and collaboration, join pianist Aaron Diehl, an artist quietly re-defining the lines between jazz and classical, onstage at the Martin Theatre. The group performs excerpts from jazz titan Mary Lou Williams’ Zodiac Suite, on the tail of recording this “joyous, enchanting creation” (The Guardian). That publication continued that “the moods crammed into each sign’s three minutes are a wonder, the playing – and on Pisces operatic singing – inspired. A triumph.” The orchestra presents the Ravinia premiere of Louise Farrenc’s Finale-Allegro from Symphony No. 3 in G Minor, and concludes the program with Beethoven’s Symphony No. 6, “Pastoral.”
