Is the art world in crisis, or just in flux? Either way, it’s worth considering these words from art commentator Matthew Collings apropos the graffiti-iste of the moment: “Banksy being considered a ‘conceptual artist’ is only a measure of how banal and feeble the ‘concepts’ of contemporary art are, and an indication of art’s slide into all-out philistinism. To appear tuned-in we now have to pretend that a literal crack in the floor at Tate Modern means global unease (the latest commission by Tate Modern in its annual Unilever series), that a lot of real people standing on a marble plinth means ‘humanity’ (Anthony Gormley’s proposal for a new work on the fourth plinth in Trafalgar Square), and that Marc Quinn’s new sculptures at White Cube of fetuses are ‘influenced by Michelangelo.’”
