Tonight's the opening night for the Philadelphia Orchestra's 2014 subscription season. For the musicians, this week has been all practice, practice and more practice. But for Music Director Yannick Nézet-Séguin, the week has had a different sound. He's this week's guest on Recap.

The orchestra will be performing Beethoven's Ninth Symphony, the "Choral," with the Westminster Symphonic Choir directed by Joe Miller, and vocal soloists Twyla Robinson, Mihoko Fujimura, Chrisitian Elsner, and Shenyang.  The program also includes Beethoven’s setting of Goethe’s Calm Sea and Prosperous Voyage and the world premiere of American composer Nico Muhly’s newly-orchestrated Bright Mass with Canons for chorus, orchestra, and featuring the Fred J. Cooper Memorial Organ.
