On March 13, the internationally famous Mark Morris Dance Group will once again bring one of its namesake choreographer’s most influential pieces, L’Allegro, il Penseroso ed il Moderato, to Cal Performances at Zellerbach Hall (UC Berkeley). Back by popular demand, this will be the fifth time that Cal Performances presents the production since its Bay Area debut in 1988. The widely acclaimed choreographic ode to darkness and light involves 27 dancers and is set to an oratorio by George Frideric Handel, which will be performed by the Philharmonia Baroque Orchestra and Chorus. Ahead of the performance, the Mark Morris Dance Group will lead an all-ages dance class featuring techniques from the piece on Saturday, March 12, from 11 a.m. to noon in the Bancroft Studio on the UC Berkeley campus. On the same day, from 2–5 p.m., Morris, Philharmonia Baroque Orchestra conductor Nicholas McGegan, and Juilliard School provost Ara Guzelimian will discuss Handel’s music at Zellerbach Hall. Both events are free and open to the public.
