With David Hockney: Current, the NGV has made the unusual decision to devote a major exhibition to a selection of work from the last decade by a 79 year-old artist active since the early 1960s. Perhaps this can be explained by the popular appeal of the iPhone and iPad drawings that make up much of David Hockney's output in this period, but the choice is interesting insofar as the narrow focus directs our attention to a body of work that would undoubtedly appear as a mere afterthought if seen in a retrospective exhibition that also included Hockney's best paintings of the 1960s and 1970s.
