Excerpt from the book The Struggle for Philippine Art, by Purita Kalaw Ledesma, published by Vera-Reyes Inc. in 1974.

The page shows a photograph of one of Roberto Chabet's earliest installations using plywood, titled An Environmental Work. The work was exhibited under the same title at the Cultural Center of the Philippines Main Gallery from 14 - 25 November 1972. It is made from rotating pale blue plywood planks, suspended from pivots on the ceiling and lit with various coloured spotlights.

In Ledesma's book, Chabet's work is labelled 'Anti-Museum Art'. He is identified as part of 'the new generation of Philippine artists that includes an avant-garde group whose art is free-wheeling and spontaneous. Their works are ephemeral and transitory. Their works are not easy to classify for they blend painting with sculpture -- and they may make use of anything they can lay their hands on.'
