They are more used to performing to packed stadiums, but stars of rock and pop are now turning their attention to other arenas. When the Pet Shop Boys' first ballet score is performed at Sadler's Wells in London next month it will be the first of a glut of productions featuring music written by mainstream popular artists. Others include Ghost: The Musical from Eurythmics' Dave Stewart and an opera, The Tell-Tale Heart, by Stewart Copeland, the former Police drummer.
Alison Duthie, head of the Royal Opera House's ROH2 programme, which commissioned Copeland for its OperaShots series, says there has been a growth in "crossover work" in recent years.
"It can be the most exciting area because it's asking people to do something very different from where they are comfortable," she says.

The National Theatre's current production Frankenstein features a score by the electronic band Underworld. Matthew Scott, the theatre's head of music, says that commissioning musicians who do not usually write for the stage is a way of attracting new audiences. But, he warns, "you can get seriously unstuck if you cast the wrong composer for the wrong project".
The Spinal Tap musician, best known for voicing characters in The Simpsons, is in talks to bring J Edgar! The Musical – a comedy about the first FBI director, J Edgar Hoover, for which he wrote the lyrics and book – to London. Shearer, twice nominated for a Grammy for best comedy album, may also write some new music for the production.
A new musical with music and lyrics by the American singer-songwriter will open at London's National Theatre in April 2012. Playwright Samuel Adamson will write the script and additional lyrics for the as yet untitled production, which is based on George MacDonald's story The Light Princess. Marianne Elliott will direct.
Sir Paul McCartney
The Beatles legend announced last week that he is collaborating with New York City Ballet's Peter Martins on a new work for the company that will premiere in September. Ocean's Kingdom is his first orchestral score for dance. "What was interesting was writing music that meant something expressively rather than just writing a song," he said.
The former Busted member's Loserville is being optioned for a West End run. Youth Music Theatre UK is staging his musical Out There at South Hill Park Arts Centre, Bracknell, in August. "If you look at Wicked and the new musicals coming out, the ones that are really working are the ones that are more pop," he said.

Bridget Jones: The Musical, which Helen Fielding has adapted from her original chick-lit phenomenon, is currently in development following a workshop production in June.

Pet Shop Boys
Neil Tennant and Chris Lowe, who wrote songs for the Young Vic's Christmas show My Dad's a Birdman, have composed their first full-length dance score – for Javier De Frutos's The Most Incredible Thing, which opens at Sadler's Wells in London on 17 March. They said that, after writing for the club dance floor, writing music for the ballet seemed a "logical development".
