The fully restored and reinstalled Royal Festival Hall organ at London’s Southbank Centre has been unveiled following a successful campaign to raise £2.3m through a Heritage Lottery Fund grant and public donations.

Organ builders Harrison & Harrison are responsible for completion of the project and will now go about tuning and balancing the instrument’s 7,866 pipes ahead of its re-inauguration at the 'Pull Out All The Stops' organ festival – 60 years since the instrument was first performed in 1954.

Running from March 18, 2014 to June 7, 2014, Pull Out All The Stops will feature eight new works, commissioned by Southbank Centre to celebrate the return of the organ, by Sir John Tavener, Sir Peter Maxwell Davies, Neil Hannon, Martin Creed, Kaija Saariaho, Simon Holt, Terry Riley and visual artist Lynette Wallworth. The opening Gala Concert on March 18 will feature organists John Scott, Isabelle Demers, Jane Parker Smith and David Goode with trumpeter Alison Balsom and the brass sections from the Philharmonia Orchestra and London Philharmonic Orchestra. Also performed throughout the festival will be Poulenc’s Organ Concerto, Saint-Saëns’s Organ Symphony, Strauss’s Also sprach Zarathustra and Alpine Symphony, and Janáček’s Glagolitic Mass.
