Erasure by an artist has been around for what I can only assume is forever, whether the intent is obvious, a means to alter meaning or merely a way to obfuscate an idea it is a seemingly cyclical approach to expression. Rauschenberg famously produced a work of art purely be erasure in 1963 – rather than adding marks to an existing work he chose instead to erase those of another – 40 erasers later – he had created “Erased de Kooning”, which is now in the collection of SFMOMA. Ron English just purchased Banksy’s Slave Labour, for $730,000 US, a painting intended for the street, that was cut out of the wall and ended up at auction in Miami . English is vowing to whitewash the piece, to erase it, as a form of protest against the monetization of street art. He is quoted as saying “we don’t make street art to have it ripped off the wall and sold. They’re not baubles for billionaires”. And finally Eddie Martinez has a new body of work, “White Outs”, showing at the Bronx Museum. Martinez who works in vibrant hues merges references to both mid 20th century abstraction and contemporary street art. This latest work looks different as he is whiting out parts of his composition to create a new one inspired by the shapes and forms that have been painted over – erased – on the street. These are ghostly in comparison to the vibrancy of his earlier work, yet they have a lovely, subtle energy to them.
