Two outstanding 20th-century operas by Catalan and French authors, respectively, share the bill at the Liceu. The operas are short, small-format and with few soloists onstage. The main roles go to Ángeles Blancas (Montsalvatge) and María Bayo (Poulenc). Also performing in the former are Mario Vittorio Prato, Antonio Comas and María Bayo. Pablo González conducts the orchestra (OBC) and the Coro del Liceu choir, while Paco Azorín manages stage direction.
