The five concerts of the chamber music cycle of the Palau de la Música Catalana explore the limits of classical, and the purest virtuosity and musicality of its performers. The essence of music in the hands of quartets and duets that mark the thread that goes from classicism to the 21st century. From the beauty and formal perfection to the emotional agitation and experimentation of the scores. Haydn, Brahms, Shostakovich, Messiaen, Widmann ... Authentic music alchemists call us to share with them introspective sessions, and explosive and unpredictable collaborations.
