The Royal Academy of Arts will host an exhibition of the works of Richard Diebenkorn.   Revered as one of the great post-war masters in his native United States, Richard Diebenkorn is an artist whose staunchly independent career takes us from abstraction to figuration and back again.  He is described by the Washington Post as one of America’s “finest abstract painters."

The artist Yoko Ono, who turned 91 in February, has enjoyed a successful—if notorious—career over seven decades. She spent the seventies as the wife of Beatle John Lennon until his assassination in New York in 1980, and appropriately for British audiences, that part of her life forms the core of her current exhibition, 'Music of the Mind' at Tate Modern.
