During his study at the Gerrit Rietveld Academy in Amsterdam (1981-1983) Bart Drost discovered the 'bitumen paper'. A material that was used in the roofing world. It was cheap, it was sold to the role, it was strong. For a background, so quickly to work on, it proved to be a splendid material for Drost. Making signs turned out to making paintings. Making quick notes. Initially with Jet Black, later Indian ink, gesso and acrylic paint. This quick painting is for Drost everytime again like a 'come home'. No chance to think, freedom to intervene. Until this very moment Drost paints with periods on bitumen paper his well-known figures. Maybe it's the only thing that's really important?
