Geometric abstraction, and an uncompromising constructivist agenda of paint about paint and colour for colour's sake, are Webb's defining characteristics. Provence II (pictured) is a prime example. At Sainsbury Centre for Visual Arts, from 27 September until 4 December 2011 Photograph: PR
Staged in part-darkness, this show brings together the work of 10 internationally acclaimed artists whose technical trickery is brought to bear on notions of darkness and shadow. Complementing the whole is a range of ominous works by artists as diverse as Rembrandt and Francis Bacon (whose 1951 portrait of Lucian Freud is featured).

Bainbridge's sculptural compositions are nothing if not eclectic. Fake fur, chipboard, knick-knacks – they're all fair game. Here the focus is on the sculptor's irreverent video works. At CIRCA Screen until 21 October 2011 Photograph: PR
This year, the annual open-submission show by art students and recent graduates kicks off in Sheffield.

Not one for roped-off museum pieces, the Mexican's sculptures always acknowledge the human factor (such as his metal works that doubled as ashtrays outside Frieze Art Fair a few years ago, pictured). Here, there are sculptures-cum-plinths for emergency blankets, soap and plastic sheeting: apt pieces for an unstable world.

It's about time a show tackled postmodernism. The emphasis here is the interest in style over substance that emerged in the 1970s and 80s. History was treated as an atemporal free-for-all by maverick collagists from Andy Warhol to Jeff Koons and magazine designers April Greiman and Jayme Odgers (who produced Wet Magazine, pictured).

Bristol's landmark art gallery celebrates its 50th birthday with a show about artists' museums, including Peter Blake's singular museum of curiosities, Marcel Duchamp's museum in a suitcase and Marcel Broodthaers's Museum of Modern Art: Department of Eagles (featuring Miroir d'Epoque Regency, 1973, pictured). At Arnolfini from 24 September until 19 November 2011 Photograph: PR
A survey of works by art's unrivalled pleasure specialist. Her video installations are awash with kaleidoscopic fields of flowers, flesh bared in kooky sex scenes, and – in one famous work – a woman who smashes car windows with a giant torch lily before sharing a smile with a cop (Ever Is Over All, 1997, pictured). But her work has more serious undercurrents than the razzle-dazzle suggests. At Hayward Gallery, SE1, 28 September until 8 January 2012 Photograph: PR
