The memorial exhibition at Tate Modern consists of works by 18 of the artists who meant the most to him, the earliest being Cézanne, the most recent Jeff Koons. It is misconceived, and gives us no sense of Sylvester's strengths as a critic and curator. Disparate works are crammed into three small rooms right in the middle of the fifth-floor galleries, so the displays are barely distinguishable from any other in Tate Modern. What Sylvester thought of these artists is unclear, because there are no substantial captions or gallery guide. All we get is a few garbled gobbets of his writing fixed to the walls outside the exhibition. Even worse, two films on Bacon and Giacometti are being shown in broom-cupboard-sized rooms and, due to the proximity of Tate Modern's plumbing, their soundtracks are periodically drowned out by the noise of flushing lavatories.
