The composers of this year's (14) Oscar-nominated film scores are set to join forces for a very special concert in Los Angeles a week before the Academy Awards.

In the first-ever Oscar Concert, William Butler, Owen Pallett, Alexandre Desplat, Thomas Newman, Steven Price and John Williams will conduct and direct their compositions at Royce Hall on 27 February (14).

Butler and Pallett are Oscar nominated for their work in Her, Desplat for Philomena, Newman for Saving Mr. Banks, Price for Gravity and Williams for The Book Thief.

The concert will also feature this year's nominated original songs, including Frozen's Let It Go, and Pharrell Williams' Happy from Despicable Me 2, which will be performed by Jill Scott.

The Oscars take place on 2 March (14).
