Question: What profeesion do Giacomo Benvenuti and Claudio Monteverdi share?

<P0-S0> These lists show the audio and visual recordings of the opera "L'Orfeo" by Claudio Monteverdi. <P0-S1>  The opera was first performed in Mantua in 1607, at the court of Duke Vincenzo Gonzaga, and is one of the earliest of all operas. <P0-S2>  The first recording of "L'Orfeo" was issued in 1939, a freely adapted version of Monteverdi's music edited by Giacomo Benvenuti, given by the orchestra of La Scala Milan conducted by Ferrucio Calusio. <P0-S3>  In 1949 the Berlin Radio Orchestra under Helmut Koch recorded the complete opera, on long-playing records (LPs). <P0-S4>  The advent of LP recordings was, as Harold Schonberg later wrote, an important factor in the postwar revival of interest in Renaissance and Baroque music, and from the mid-1950s recordings of "L'Orfeo" have been issued on many labels. <P0-S5>  Koch's landmark version was reissued in 1962, when it was compared unfavourably with others that had by then been issued. <P0-S6>  The 1969 recording by Nicholas Harnoncourt and the Vienna Concentus Musicus, using Harnoncourt's edition based on period instruments, was praised for "making Monteverdi's music sound something like the way he imagined". <P0-S7>  In 1981 Siegfried Heinrich, with the Early Music Studio of the Hesse Chamber Orchestra, recorded a version which re-created the original Striggio libretto ending, adding music from Monteverdi's 1616 ballet "Tirsi e Clori" for the Bacchante scenes. <P0-S8>  Among more recent recordings, that of Emmanuelle Haïm has been praised for its dramatic effect. <P0-S9>  The 21st century has seen the issue of an increasing number of recordings on DVD. <SEP> <P1-S0> Sergio Vartolo (Bologna, 1944) is an Italian harpsichordist, organist, musicologist and conductor; in past also active as countertenor. <P1-S1>  In 1996 he was appointed maestro de capella of the Cappella Musicale di San Petronio di Bologna founded in 1436. <P1-S2>  He has an extensive discography, both as a harpsichordist - the complete works of Girolamo Frescobaldi, and as a conductor - particularly works by Giovanni Paolo Colonna and Giacomo Antonio Perti associated with San Petronio, but also operas by Claudio Monteverdi and others. <SEP> <P2-S0> Claudio Giovanni Antonio Monteverdi (] ; 15 May 1567 (baptized) – 29 November 1643) was an Italian composer, string player and choirmaster. <P2-S1>  A composer of both secular and sacred music, and a pioneer in the development of opera, he is considered a crucial transitional figure between the Renaissance and the Baroque periods of music history. <SEP> <P3-S0> Giacomo Benvenuti (16 March 1885, Toscolano — 20 January 1943, Barbarano-Salò) was an Italian composer and musicologist. <P3-S1>  He was the son of organist Cristoforo Benvenuti and studied at the Liceo Musicale in Bologna under Luigi Torchi (musicology) and Marco Enrico Bossi (organ). <P3-S2>  In 1919 his collection of songs for voice and piano accompaniment, "Canti a una voce : con accompagnamento di pianoforte", was published in Bologna. <P3-S3>  In 1922 he published a collection of 17th-century art songs entitled "35 Arie di vari autori del secolo XVII". <P3-S4>  Composer Samuel Barber studied the works of Giulio Caccini, Andrea Falconieri, and other early Italian composers under his tutelage in Milan in 1933-1934. <P3-S5>  For the Teatro dell'Opera di Roma he adapted Claudio Monteverdi's "L'Orfeo" for a production which premiered on 27 December 1934. <P3-S6>  The adaptation was later used for the first recording of "L'Orfeo" in 1939, which included a performance by the orchestra of La Scala Milan under conductor Ferrucio Calusio.
