This week I have been reminded of the work of Yves Klein (1928-1962) who is perhaps best remembered as a painter of blue monochrome paintings. More specifically, he is known for the particular shade of blue paint employed in his paintings and sculptures, the trademarked International Klein Blue (IKB).
But what has drawn my attention to Klein's work this week is more the conceptual side of his practice (although this is not to imply that his blue monochromes are not conceptual), especially the work in which Klein explored (and exposed) throughout many mediums what he dubbed 'the void.' To this effect, Wikipedia recounts works by Klein such as a composition with no actual composition, painting without painting, and an exhibition without any content whatsoever (his Iris Clert Gallery exhibition of April, 1958).
I've stressed in the past that where minimal art succeeds for me is in its ability to be reductive and to reveal the essence of being and matter. Klein took this to—what was at the time—extremes, and in his idiosyncratic grand and theatrical manner. We're all better off for having him.
