Philadelphia Orchestra Conductor Change

Jiří Bĕlohlávek has canceled his Philadelphia Orchestra appearances this week. An orchestra spokeswoman says the conductor has a bad back. Juanjo Mena takes over.  Soprano Karita Mattila will still sing Strauss' Four Last Songs. The Mahler "Adagio" from Symphony No. 10 also stays. But the Martinu Symphony No. 3 will be replaced by Beethoven's Symphony No. 6. Too bad, that, but we're looking forward to Mattila's debut.
