At 33, Chang is way too young to remember the disconcerting effect of the Beatles’ 1968 two-record release known as the White Album, which became an instant icon. The American-born Chang has managed to obtain over 700 of the 30 million copies sold worldwide. Stained, dog-eared, yellowing, written and drawn upon, they are displayed in a grid on the wall and gathered into bins and boxes on (and under) a long central table, collectively testifying to both the ravages of time and the pristine dream of timelessness. The show, as announced by a red neon sign in the gallery window, is called “We Buy White Albums,” and the artist means it-in every sense.
