La bohème is an opera in four acts by Giacomo Puccini to an Italian libretto by Luigi Illica and Giuseppe Giacosa, based on Scènes de la vie de bohème by Henri Murger. The world premiere performance of La bohème was in Turin on February 1, 1896 at the Teatro Regio (now the Teatro Regio di Torino) and conducted by the young Arturo Toscanini. Since then La bohème has become part of the standard Italian opera repertory and is one of the most frequently performed operas internationally. According to Opera America, it is the second most frequently performed opera in the United States, just behind another Puccini opera, Madama Butterfly. In 1946, fifty years after the opera's premiere, Toscanini conducted a performance of it on radio with the NBC Symphony Orchestra. This performance was eventually released on records and on Compact Disc. It is the only recording of a Puccini opera by its original conductor (see Recordings below). (via Wikipedia)
