The former Santa Cruz Chamber Orchestra is kicking off its first season under a new name with two energetic and attractive modern works for strings and trumpet: Arthur Honegger’s Symphony No. 2 and Shostakovich’s Piano Concerto No. 1, the latter with pianist Brenda Tom. Peteris Vasks’ solemn Cantabile for strings rounds out the intriguing program from these fine performers. Maya Barsacq conducts.
