Only this perfectly rendered symbiosis that boasts a rigorous abstract composition involoving the lyrism of vivid, singing colors [. . .] is a first rate artistic event; to be true, it is an original creation within contemporary painting.
--Mario Pedrosa, as quoted in Olívio Tavares de Araújo, "Volpi 2006: neither subterfuge, nor strategy" in exhibition catalogue Volpi: a música da cor (São Paulo: Museu de Arte Moderna de São Paulo, 2006), 258.
