Pedro Laurenz has always been related to Julio De Caro’s style, since with his cutting phrasings and his vigorous way of expressing, he gave a character of its own to the interpretative quality of De Caro’s group. Laurenz’s orchestra made its debut in 1934, being an orchestra of bright sonority and original effects, appealing harmonic elaboration and naturally influenced by the “De Caro’s style”. Laurenz was always very careful about the technical level of his collaborators, and when Osvaldo Pugliese and José Nieso left the orchestra, he replaced them by Armando Federico and Alfredo Gobbi, respectively. In latter changes of musicians, some of the artists that were part of Laurenz’s  orchestra were Héctor Grané, Miguel Jurado, Mauricio Mise, Héctor Gentile, Pedro Terrón, Francisco Oréfice, Héctor Presas, Alberto Celenza, Rolando Gavioli, Domingo Varela Conte, Milo Dojman, Ángel Domínguez, Oscar Podestá  and Carlos Parodi.
