On Feb. 1-2, the Baltimore Symphony will celebrate Maurice Ravel’s 150th birthday in a program conducted by Robert Treviño. The Ravel selections include Alborada del gracioso, Rapsodie espagnole, Pavane pour une infante défunte and La Valse, which the composer described as a “choreographic poem for orchestra.” Karen Gomyo will be the soloist for Prokofiev’s Violin Concerto No. 1.
