The star of this dramatic mixed tanda is vocalist Alfredo Del Río. As Abel Palermo notes in his biographical sketch, Del Río’s “great vocal facility, his special sense for interpretation, and his discipline and responsibility about taking care of his voice made him become a great professional.” The quality of the two Laurenz numbers–rarely heard at milongas–is not very good, but I’m not aware of any better transfers.
Update: I had assumed that combining Gobbi and Laurenz in the same tanda was uncommon, but in this recent interview renowned DJ Félix Picherna notes that he used to mix these two orchestras when DJing in Europe.
I am admittedly not a big fan of Pugliese. There is an exception to my reservations about his orchestra, however: his collaboration with Jorge Vidal. Unfortunately, Pugliese and Vidal recorded only seven tangos together (plus one milonga), so the options for a DJ are very limited. To spice things up and challenge seasoned dancers, I sometimes substitute ‘Testamento de arrabal’ with Argentino Galván’s ‘Pa’ mí es igual‘ (1951), which also features Vidal on vocals. (Galván arranged some songs for Pugliese in the mid-40’s, and his orchestra, while clearly distinct in style, shares some similarities with that of the celebrated pianist from Villa Crespo.) Another possible substitution is Galvan’s ‘Cuando yo me vaya’ for ‘La cieguita’: while musically the song doesn’t fit as nicely, the lyrics are evocative of both ‘Testamento de arrabal’ (“Tan sólo una cosa pido, que me llore un bandoneón”) and ‘Puente Alsina’ (“A la barra de Boedo, Caballito y Puente Alsina”).
