It fascinates me that exhibitions that take six months of research and soul-searching can be indistinguishable in their final effect from a selection of works made within a single day. I guess the lesson is that if you have a rich vein of work to tap, and know how to make stuff look good on a wall, a fast show can also be a good show.
Hamish McKay's current show of four Don Driver works exemplifies this approach. Quickly assembled, it's nonetheless a visually satisfying experience - complete unto itself. As a die-hard Driver fan, I have no pretensions to objectivity here; I just think you should get along to the exhibition.
