A new book about the great modernist landscape architect and designer Roberto Burle Marx (1909-1994) shows his versatility and originality. Roberto and his musician brother Walter were friends of Villa-Lobos. One of Roberto Burle Marx's Villa-Lobos legacies is the garden he designed in 1986 for the Museu Villa-Lobos.
Roberto Burle Marx also collaborated with the composer: in 1959 (the year of Villa's death) he worked on stage and costume designs for the ballet Zuimaluti, with music by Villa-Lobos, and a libretto by Mario de Andrade. I haven't been able to track down any references to this work other than the Burle Marx designs. Zuimaluti isn't included in the latest version of Villa-Lobos: Sua Obra. Have any Villa-Lobos scholars out there heard of any surviving music from this project?
Burle Marx is an amazing artist; you can see many of his designs in this preview of the new book.
