The German artist's work, finally on show in London, is an uprooted reunion of everything strange in the supposedly familiar tale of western art history
With his Gazing Balls, Koons has created a body of work that appeals to the brain as well as the eyes
Plus: Neo Rauch finally comes to London; John Wesley's odd eroticism; and Alighiero Boetti's monumental use of mementoes
Plus: Virginia Chihota’s claustrophobic blast of colour; a surreal spectacle from James Richards at the ICA; and Suzanne Treister's sinister take on technology
Plus: The final painting of Francis West; Yinka Shonibare without his trademark fabric; and Paula Rego's first tapestry
Plus: Abstract expressionism outside the RA; Njideka Akunyili Crosby at Victoria Miro; Helen Marten's rise to stardom; and Philippe Parreno in the Turbine Hall
Plus: lining up the evidence at Michael Hoppen Gallery; Fausto Melotti's ingenious sculptures; and an unsung branch of the Bauhaus
