Robert Ryman

"That so much of Ryman's art depends on such subtle effects might explain why it leaves some critics cold. Outside the gallery, it can look like an awful lot of white paint signifying very little. But with the Barbican's thoughtful curation (and an accompanying booklet mercifully free of artspeak), if there's ever been a time and place for the sceptics to see what Ryman was getting at, it's here."
