WORKS of art by one of America's greatest living artists are to be unveiled at the National Galleries of Scotland this weekend.

Photographs and paintings by Ed Ruscha will mark the first exhibition by the artist in more than a decade.

Music from the Balconies is the latest show in the Artists Rooms project, which is a collection of contemporary arts jointly owned by the National Galleries of Scotland and the Tate, gathered and led by the leading art collector and dealer Anthony d'Offay.

The show includes large paintings of American landscapes, overwritten with Ruscha's playful use of words, phrases and legends, as well as photographs of Los Angeles, his long time home and inspiration.

Ruscha is associated with the Pop Art movement, as in 1962 his work was shown alongside Roy Lichtenstein and Andy Warhol.

Unveiling the show, which runs until April 2018, Mr d'Offay said: "This is the best collection of Ruscha, probably outside America, so people will see things they cannot see anywhere else.

"I think in total we have something like 120 works in total in the Artist Rooms collection. Ed himself looks more and more like a colossal figure in art.

"It was always assumed in the US that New York for the place for art, and it was a very wonderful thing when I began to represent him, and is a wonderful person to know, so warm and so brilliant."

Ruscha was born in 1937 and is still producing new works.

The new show encompasses two rooms.

Among the photographic work on show at the Scottish National Gallery of Modern Art, is Sunset Strip Portfolio, a series of images of Sunset Strip, a mile and a half stretch on west Hollywood's Sunset Boulevard.

Paintings include The Final End from 1992, in which Ruscha plays on the end credits of Hollywood movies.

Other works include his photographs of parking lots in Los Angeles.

Mr d'Offay, whose Artist Rooms shows have now been seen by more than 40m people since they were established in 2008, added: "We can talk about banality, and what is more banal than a parking lot? But if you look at his books, which are represented in this show, they are so important, and famous, and taught.

"When you see his works, it makes you stop and think. And there is an incredible, gentle humour."
