Ibercamera closes its 41st season with a splendidly Viennese concert, featuring the Barcelona debut of Czech conductor Petr Popelka, principal conductor of a Vienna Symphony Orchestra that performed at L'Auditori on Wednesday night. To win over music-loving audiences, Popelka couldn't have chosen a better repertoire: the opening The consecration of the home, by Beethoven; the Violin Concerto, by Mendelssohn; the Dynamized vouchers, by Josef Strauss, and a suite of The Rosenkavalier, by another Strauss, in this case Richard.
