The curtain will soon go down on an exhibition of David Hockney opera sets at Salts Mill.

The four large models of Mozart’s Magic Flute, Stravinsky’s The Rake’s Progress and Stravinsky’s Le Rossignol (The Nightingale) have been on display for ten years.

The sets will be removed after closing on Sunday, July 4, and taken to Los Angeles, where the Bradford-born artist has a house and a studio.

Salts Mill director Zoe Silver said: “We’d love to see people coming back to see David’s stunning opera sets one last time. They will be there until 5pm on July 4. Then we will be working with David on an exciting new show.”

Mr Hockney, 73 on Friday, July 9, has been to the gallery to take measurements for whatever it is he has in mind.

He is now hard at work in his Bridlington studio preparing for perhaps the largest exhibition of his life in 2012. London’s Royal Academy is giving over the whole of its downstairs space to show the East Yorkshire landscapes Hockney has been painting for the last six years.
