A quite rare gem and a must for all Carlos Di Sarli lovers: This album was released posthumously as a doble 33-RPM vinyl record around 1960-61. Philips recorded the voice of Edmundo Rivero and replaced Jorge Durán who sings on the earlier well-known recordings. Technically quite easy, as Philips used tape masters for all their Di Sarli recordings of the 1950s. Most likely the orchestra was recorded on one channel of the tape and the singer on the other. Hence the obvious singer replacement in karaoke style. On the other hand, quite challenging for Edmundo Rivero who excels in dubbing his voice and emotion on these recordings! The album contains four tracks: Nubes de humo, Si nos queremos todavía, Por quererla así and ¿Dónde estás?
