Chorus on high in Brahms work at Strathmore

As music director of the Baltimore Symphony Orchestra, Marin Alsop's greatest strength is not necessarily a certain swath of music from the classical and romantic core. The ensemble's new principal guest conductor, Markus Stenz, has built a reputation in those areas. After a concert devoted to Mozart in October, Stenz led a vivid and moving account of the "German Requiem" of Johannes Brahms in the Music Center at Strathmore on Saturday evening.
