The present restoration project makes available as high resolution downloads the complete 84 recordings of «Carlos Di Sarli y su Orquesta» between 1951 and 1954. They have been produced at the then newly established Music-Hall record label in Buenos Aires. This label marks an important milestone in Argentine recorded music production which was until then pressed on 78-rpm shellac records. Music-Hall achieved the first Argentine commercial recording with a reel-to-reel tape recorder and a resulting vinyl record production. They were at least one year ahead of Odeon and RCA Victor, the two until then dominating major labels. To the press, Music-Hall announced Carlos Di Sarli as the first Argentine tango artist ever to be published on the new vinyl format. The records are still in mono but the tape master brings a new flexibility and mobility into the recording process. The studio and the record plant can now be easily at different locations. Another advantage of the new medium is the much lower background noise and therefore slightly higher dynamic range: Music-Hall advertised the sound of their records on the sleeves as fidelidad que iguala a la realidad, fidelity that equals reality. Nowadays we would maybe use the term high fidelity. This is the album release containing all 84 restored tracks.
