The St. Mary’s College of Maryland’s River Concert July 22 offers a colorful evening of music: Concertgoers will hear Gustav Mahler’s Symphony No. 1, “The Titan,” and St. Mary’s College composer David Froom will introduce a new work, “Amichai Songs,” featuring baritone William Sharp. The Chesapeake Orchestra directed by Jeffrey Silberschlag will also perform Leonard Bernstein’s “Dance Variations” and feature violinst Jose Cueto in a performance of Judah Adashi’s “Grace.” The weekly celebrations on the college’s Townhouse Green continue every Friday through July 29 with world-class music and a variety of food from local vendors. Gates open at 5 p.m. and concerts start at 7 p.m. The outdoor concerts are free and open to the public, and picnic baskets are welcome. For more information, visit the River Concert Series’ web site.
