Mollo is best known as the guitarist for Sumo from 1984 until the band's dissolution after Luca Prodan's death in 1987 and, shortly thereafter, a co-founder of Divididos.

[1] Ricardo Jorge Mollo was born in the Pergamino neighbourhood of Buenos Aires, Argentina on 17 August, 1957, but moved to El Palomar early in his life.

Mollo's passion for the guitar first started when a friend, at the age of thirteen, introduced him to the works of Jimi Hendrix.

After Sumo dissolved, with fellow-bandmate bassist Diego Arnedo, Mollo formed the band Divididos.

[4][5] Besides his work as a musician, he is a producer and has collaborated with several Latin American artists including Cuca, León Gieco, Charly García, Gustavo Cerati, Los Piojos, Las Pelotas, La Renga, and Luis Alberto Spinetta.
