New CD Sealed. Llegando los Monos by SUMO is considered the #22 best album in the history of Argentine rock by the Magazine list Rolling Stone.
The album was self-produced by Sumo, with Mario Breuer as operator, although Walter Fresco is the one who appears as artistic director. The biggest hit from this album was "Los Viejos Vinagres", which Luca Prodan said was a purposely composed hit. The album was presented on August 9, 1986 at Obras Sanitarias and was filmed for the 55-minute short film called Sumo en Obras.
