PHILADELPHIA ORCHESTRA at Mann Center for the Performing Arts, 52nd Street and Parkside Avenue. 8 tonight. Tickets: $10-$68. Info: 215-893-1999.
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.
