La Siniestra is cataloged within the most relevant groups of current tango according to the Argentine press. Its sound is distinguished by its deep timbral depth and a natural ensemble between all the instruments, reflecting the years of careful and constant exploration, both in the field of academia and on the street, so necessary for this genre. The group has consolidated with more than 10 years of experience and comes to perform several times at the Tango Festival and World Cup of Buenos Aires and the most important concert halls in Argentina.
