Giuseppe Giacosa in the context of "Luigi Illica"

Rent (stylized in all caps) is a rock musical with music, lyrics, and book by Jonathan Larson. Loosely based on the 1896 opera La bohème by Giacomo Puccini, Luigi Illica, and Giuseppe Giacosa, it tells the story of a group of impoverished young artists struggling to survive and create a life in Lower Manhattan's East Village, in the thriving days of the bohemian culture of Alphabet City, under the shadow of HIV/AIDS.

The musical was first seen in 1993 in a workshop production at New York Theatre Workshop, the off-Broadway theatre which was also where the musical began performances on January 26, 1996. The show's creator, Jonathan Larson, had died suddenly of an aortic dissection the night before. The musical moved to Broadway's larger Nederlander Theatre on April 29, 1996.

Tosca is an opera in three acts by Giacomo Puccini to an Italian libretto by Luigi Illica and Giuseppe Giacosa. It premiered at the Teatro Costanzi in Rome on 14 January 1900. The work, based on Victorien Sardou's 1887 French-language dramatic play, La Tosca, is a melodramatic piece set in Rome in June 1800, with the Kingdom of Naples's control of Rome threatened by Napoleon's invasion of Italy. It contains depictions of torture, murder, and suicide, as well as some of Puccini's best-known lyrical arias.

Puccini saw Sardou's play when it was touring Italy in 1889 and, after some vacillation, obtained the rights to turn the work into an opera in 1895. Turning the wordy French play into a succinct Italian opera took four years, during which the composer repeatedly argued with his librettists and publisher. Tosca premiered at a time of unrest in Rome, and its first performance was delayed for a day for fear of disturbances. Despite indifferent reviews from the critics, the opera was an immediate success with the public.
