Watch Full Movie Online. I Lombardi alla prima crociata (The Lombards on the First Crusade) was Verdi’s fourth opera and received its first performance at La Scala, Milan, in February 1843. The grandiloquent subject matter is fleshed-out with broad-brushed musical and dramatic effects and lavish choral scenes created a correspondingly impressive impact. A great success in Milan, it spread to the rest of Europe within a matter of only a few years.
