Conductor Carlos Kalmar finishes up his Mann week with two revered works from the center of the repertory.
He's chosen the Symphony No. 2 by Jan Sibelius, the most familiar of seven by a composer with close ties to this orchestra. Its Finnish heart, full of long-spun melodies that erupt like flowers through wintry ice, and a triumphant finale, has made this symphony an audience favorite for a century.
