The work and style which Gustavo Naveira and Fabián Salas began was augmented by their now famous student, Mariano Frumboli (a.k.a. "Chicho").
He presents a new attitude and style that is part of the new breath of fresh air in tango. It is safe to say Chicho is the single most-influential new stylist and teacher in the tango world in the last 5 years.
His signature is perhaps how he interprets/embellishes the rhythm.
Chicho makes modern tango seem accessible.
Also a very talented visual artist. Take a look at his paintings ...
