Richard Diebenkorn at the Royal Academy reviewed: among the best visual evocations of LA there are

It is true that, like wine, certain artists don’t travel. Richard Diebenkorn, subject of the spring exhibition in the Royal Academy’s Sackler Wing, is a case in point: an American painter who is revered in his native land, but of whom few will have heard over here. Will the RA show change that, and — more crucially — does it deserve to? Up to a point.
