Performer: Chamber Chorus of the Palau de la Música Catalana

In Los Angeles, Gustavo Dudamel conducts Beethoven's Missa solemnis for the first time... and it proves worth the wait. 

Christoph Prégardien joins Il Gardellino on tour in Amsterdam with Bach's four of the cantatas from the Christmas Oratorio. 

Contrasting sensations at the Liceu, where the audience punished a production of La bohème with boos and gave rapturous applause to a cast that performed at half throttle.
