The London Festival Orchestra (LFO) was an independent orchestra active as early as 1967 and conducted by Ross Pople. In the world of pop music, the orchestra was best known for providing accompaniment to the Moody Blues for their landmark 1967 album Days of Future Passed, when it was the house band for Decca Records under Peter Knight.

With the staging of the orchestra's summer festival of music in cathedrals, under the title Cathedral Classics, sponsored by American Express and British Gas, London Festival Orchestra quickly became a household name in the UK and abroad. In 1994 Pople's vision of artistic independence inspired the creation of The Warehouse; making LFO the first British orchestra to own a permanent, independent home. The Warehouse, situated in the heart of the South Bank, is a state of the art rehearsal, recording and concert venue and a significant focal point for UK and international artists and orchestras where they rehearse, perform and record. This is also where the LFO musicians are showcased in various collaborations as The Warehouse Ensemble with in-house performances.

BMG's new classical music label Arte Nova contracted LFO to record the bulk of its new classical music label in the late 90s. The LFO's enviable discography also includes recordings for Deutsche Grammophon, Hyperion and ASV.

Additional to the LFO's London concert seasons at the Southbank Centre and the Barbican Centre, and more recently the Cadogan Hall, the Orchestra has a long history of touring in the Far East, the Middle East and the Americas; at the Seoul Olympics; as cultural ambassadors to Argentina at the resolution of the Falkland Conflict; with annual tours to Germany, France and the Netherlands.

The LFO was also featured in a 2004 episode of architectural show Grand Designs due to its objections to the colour of the brick in a neighbouring building.
