This picture shows Carlos Di Sarli, who was not only leading an orchestra but also composing music, collaborating with the lyricist Homero Manzi, one of the leading figures of tango poetry and co-author of many important dance tracks in the milongas nowadays. This scene below is representative for the way tangos were born: usually, it was a product of teamwork by a musician and a poet, although the musicians weren’t always necessarily important orchestra directors like Di Sarli.
This photo reminds me of the story that Di Sarli never allowed any filming of his hands playing piano. What a thrill it would be to see the Lo
finishing the sentence: to see the lord of the tango playing his music at the piano.
