In Concert with the London Symphony Orchestra

In Concert with the London Symphony Orchestra is a live DVD by British hard rock band Deep Purple, featuring a recording of the band from 25 September and 26 September 1999 at the Royal Albert Hall in London with the London Symphony Orchestra, and released on 8 February 2000 on Spitfire records.

The concert shown in the DVD was a project started in 1999 by keyboardist Jon Lord, who sought to recreate the band's innovative 1969 album, Concerto for Group and Orchestra, of which the original score was lost. With the help of Marco de Goeij, a Dutch fan who was also a musicologist and composer, the two painstakingly recreated the lost score, and Lord elected to have the band perform it once more at the Royal Albert Hall, but this time with the London Symphony Orchestra rather than the Royal Philharmonic Orchestra, and with Paul Mann as conductor rather than Malcolm Arnold. The concert also featured songs from each member's solo careers, as well as a short Deep Purple set, and guest musicians such as Ronnie James Dio, the Steve Morse Band, and Sam Brown. In early 2001, two similar concerts were also performed in Tokyo, and were released as part of the Soundboard Series box set.

A CD album of the recording was also released, entitled Live at the Royal Albert Hall.
