Amidst the discussions in the street and in the press about the assembly of Lohengrin at the LyceumOn days of concert season launches for the next academic year, and on a rainy day with the winds rising at the gates of spring, attending the peace of a Quartet Casals concert is a soothing relief from so much outside noise. And yes, the members of the chamber ensemble have done it again: that is, achieving the complicity and communion of the acolyte audience with an exquisite, well-crafted program, and above all with the incentive of attending Cristina Cordero's first viola performance, after Jonathan Brown had left the quartet. All this, in the modernist hall of the Palau de la Música.
