Macbeth (opera)
Verdi wrote several works based on Shakespeare plays.  Macbeth was the first of these.  It was composed in 1847, at a time when he was composing a lot of operas.  In those days Italian operas were always about a love story, but Macbeth was unusual because there was no love story.  Instead, it is a story about wanting power, even if means murder.  The opera helped to make him very famous, and it has remained one of his most popular operas.
