Cetra was an Italian record company, active between 1933 and 1957, the year in which, by merging with Fonit (Fonodisco Italiano Trevisan), it gave birth to Fonit Cetra. Its roster of artists included Maria Callas, Renata Tebaldi, Lina Pagliughi, Ebe Stignani, Carlo Bergonzi, Galliano Masini, Giovanni Malipiero, Ferruccio Tagliavini, Carlo Tagliabue, Rolando Panerai, Italo Tajo, Giuseppe Taddei, Tancredi Pasero and Cesare Siepi, among other leading Italian opera singers. The company was notable for issuing many recordings of obscure or seldom heard operas and the more obscure operas of Giuseppe Verdi to coincide with the 50th anniversary of the composer's 1901 death in 1951. Cetra recordings are often now reissued by the company Fonit Cetra. Cetra opera albums were first distributed in the United States on the Cetra-Soria label (founded by Dario and Dorle Soria, who later founded Angel Records). Beginning in 1966, several Cetra opera recordings were distributed in the U.S. by Everest Records. Cetra also produced popular music recordings from at least the World War II years through the 1960s. One of their instrumental artists is accordionist Michele Corino, a soloist with Italy's prominent Angelini Orchestrauntil he moved to San Francisco (California), in 1948. "Mike" ran a prominent accordion studio in "North Beach Music" (a.k.a. Corino Music) and taught, worked and recorded with brothers Fabio and Gianfranco Giotta, part of the San Francisco-based Caffé Trieste (see also "Cavalier Records", "Caffé Trieste" and "Trieste Records"). Gianfranco shared the studio with Mike on the 1963 Cetra album titled "Rome to Paris". History of the Cetra C.e.t.r.a. (the name is the acronym of Compagnia per edizioni, teatro, registrazioni ed affini) was born in Turin on April 10, 1933 on the initiative of the Italian Agency for Radio Auditions (EIAR), which decides to transform the Edizioni musicali Radiofono, active since 15 September 1923 (and owned by him) in the record company, changing its name to Cetra Società Anonima; later the company will become a joint stock company. Initially, the Cetra only made its own recordings and the distribution of the discs, for the printing of which it used instead of the Parlophon as easily found on the labels. In a short time, also starting the printing of its own records and with its own machinery, it became one of the leading companies in the Italian discography (at the time only 78 rpm records were printed), thanks above all to the link with the
