Assassinio nella cattedrale (Murder in the Cathedral) is an opera in two acts and an intermezzo by the Italian composer Ildebrando Pizzetti. The libretto is an adaptation by the composer of an Italian translation of T.S. Eliot's play Murder in the Cathedral. The opera was first performed at La Scala, Milan on 1 March 1958.

Pietro Mascagni's opera recorded in 2009. Conductor Stefano Ranzani leads the orchestra and chorus of the Zurich Opera House, with performances by Argentinian tenor Jose Cura and soprano Pauletta Marrocu.

This hard-edged postmodern production of Giuseppe Verdi's haunting masterpiece brings the story of Shakespeare's bloody tragedy to vivid life, characterized by spine-tingling atmospherics and a triumphant debut by American baritone Thomas Hampson in the title role. This Zurich Opera House production also features a mesmerizing turn by Paoletta Marrocu as the beautiful, power-hungry Lady Macbeth, while striking sets and costumes further enhance the duality of the main character whose rise and fall mirror the darkest impulses of man. Replete with supernatural mystery, sexual tension, and violent power plays, this timeless story remains gripping and chilling for today's audiences and boasts some of the most astonishing music of Verdi's legendary body of work.

Following the runaway success of Cavalleria rusticana in 1890 at the age of 27, Mascagni did not rest on his laurels. In just a few years, he completed five operas, including Iris, premiered at the Teatro Costanzi in Rome in 1898. Mascagni might well have taken for his own Puccini's famous quip, “Against everything and everyone, make a work from melody”. And in Iris it is melodic invention which shows the composer's genius at its greatest. A melody by Mascagni is usually long, smooth and Italian-sounding; and Iris is full-on melody all the way, particularly in such crowd-pleasers as Jor's Serenade, the “Hymn of the Sun” or the duet in Act II “Oh come al tuo sottile corpo s'aggira”, which includes the famous “Piovra”. Furtheremore, with a little effort listeners can identify what would be the various musical “numbers”. In Iris, Mascagni is almost obsessively attentive to recitative and his exemplary flexibility at times recalls the sublime "conversation style" "invented" by Puccini.
