Enrico Caruso was an Italian operatic first lyric tenor then dramatic tenor. He sang to great acclaim at the major opera houses of Europe and the Americas, appearing in a wide variety of roles that ranged from the lyric to the dramatic. One of the first major singing talents to be commercially recorded, Caruso made 247 commercially released recordings from 1902 to 1920, which made him an internationally popular entertainment star.

Opera is a form of theatre in which music is a fundamental component and dramatic roles are taken by singers. Such a "work" is typically a collaboration between a composer and a librettist and incorporates a number of the performing arts, such as acting, scenery, costume, and sometimes dance or ballet. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor. Although musical theatre is closely related to opera, the two are considered to be distinct from one another.
