Bassi's work deals with drama and arcane resonances charged with nostalgia for the primitive and appeals to the unconscious. To fulfill those desires Bassi gives shape to signs. He works on flat surfaces and occasionally in three dimensions, creating sculptures (a head or a jar). His most frequent signs are crosses, heads, animals, pots, superimpositions of large forms and their smaller duplicates, blindfolded characters and masks.

Since 1990, Bassi has participated in different group shows in Uruguay, Ecuador and Bolivia, as well as in various plastic arts projects. Bassi’s solo exhibitions include: Guardianes de Zobeida, Galería del Notariado, Montevideo, 1992; Muhkuh, Playa de Chen-Cho-Mac, Mexico, 1993; Tinieblas Primordiales, Museo y Archivo Histórico Municipal-Cabildo, Montevideo, 1995; Tinctur, Espace Place des Petits Murs, Nantes, France. His group shows include: 2003 Galería Ibere Camargo, Porto Alegre, Brasil; 2001 at the VII Bienal de la Habana and The Corcoran College or Art and Design. Washington D.C. USA.
