This work includes text by Penelope Curtis. Imi Knoebel re-visits his founding vocabulary by showing and reworking the key works he made after his study alongside Joseph Beuys in Dusseldorf in 1968. This exhibition shows a number of key pieces which constituted his original practice. The works, from the late 1960s and early 1970s, highlight the importance of support and the addition of line, colour or light. They will be shown in their original format, or where the technology has changed, in the most appropriate form for today. Despite his international reputation Knoebel's work has rarely been seen in this country. Displaying early and recent works this exhibition examines the relationship between painting and sculpture, demonstrating not only the constructed quality of painting, but also the relationship between painting and installation. This catalogue accompanies the exhibition Imi Knoebel at Henry Moore Institute, Leeds, 24 September - 16 December 2006.
