Robert Lambermont is both a pianist and a visual artist and graduated from the Gerrit Rietveld Academy in Amsterdam in 1999. In the spatial, kinetic objects that Lambermont makes, similarities in content can be recognized with the music of Simeon ten Holt. As a pianist, Robert Lambermont specializes in this composer, with whom he maintained a close relationship for fifteen years. Simeon ten Holt wrote in his memoirs: “Robert understood best that the performance of the full-length pieces (after Canto Ostinato) cannot simply be arranged with a few rehearsals or by skilled pianists, but presupposes a maturing period that amounts to a difficult process of conquest.” Lambermont's sculptures are included in various collections of museums and collectors at home and abroad, including the Dutch National Collection, the Bonnefantenmuseum Maastricht and Musica Klankenbos in Neerpelt, Belgium. Over the years, Robert Lambermont received several stipends from the Mondriaan Fund.
