This is surely one of the most well-known tangos of Piazzolla, here in an arrangement for double bass and guitar of the Argentine bassist Andrés Martin, who worked on this piece also for double bass and harp as well as for double bass and piano. One can admire this version with guitar in an impressive video on YouTube in the Internet, in which Andrés Martin himself plays the double bass. The note sheets of the other two versions are likewise available here in the PRObass Music publishing house.
