This is a mixed vals tanda built around Osmar Maderna’s exquisite “Pequeña”. I picked Calo’s version of “Jugando, jugando” because it features Maderna as pianist and the sound of the orchestra is similar to Maderna’s. However, as DJ Mary Wu pointed out to me, Lomuto’s version of that tango (with Carlos Galarce, 1944) has a kind of bittersweet quality that is present in “Pequeña”, but absent in Calo’s version. So I suggest experimenting with both versions, as I have myself done over the past few weeks at various milongas. You may also want to try substituting ‘Una vez en la vida’ (Osvaldo Fresedo with Ricardo Ruiz, 1941) for ‘Motivo de vals’ if you find the tempo of the latter unacceptably slow (personally I find that it works at some milongas but not others, depending on the energy levels).
