Felix Picherna is a legend, and he was clearly the first tango dj to make a lasting impression in me. Sitting with his cassette deck, rewinding the prepared tandas, live commenting the upcoming music with the microphone. Unforgettable.
Enjoy this video from the excellent “Tengo una pregunta para vos” series by Pepa Palazón, that I just recently found time to start watching. There are several gems there, and the most recent ones are subtitled in English (that includes this one).
