The main difference between Tubular Bells and the orchestrated version is that Oldfield does not perform the majority of instruments himself; he only plays an overdubbed guitar. All of the melodies from Tubular Bells are the same, although transferred to different instruments. Vocal chords were not performed as vocals and there is no 'master of ceremonies' reading out the instruments at the end of part one.
In 1975 New Musical Express described the album as a logical extension of the piece.[3] However, Oldfield was not happy with Bedford's orchestrated interpretation of his work, as he stated in his autobiography, Changeling.[4]
The Orchestral Tubular Bells was not the only Mike Oldfield album that was orchestrated at the time; David Bedford also wrote the score for Oldfield's second album, Hergest Ridge. However, The Orchestral Hergest Ridge was never released to the public as an album. Excerpts from The Orchestral Hergest Ridge were featured in the 1979 NASA film The Space Movie.
The album artwork depicts the "bent bell tube" image from Tubular Bells, originally by Trevor Key, in a partly blue/grey box, surrounded by a black border. Some later releases from 2003 have had the bell on a yellow/orange skyscape.
Bedford's orchestration was performed by the BBC Concert Orchestra, conducted by Michael Seal and again featuring Steve Hillage, for a concert marking what would have been Bedford's 80th year. A recording was broadcast by BBC Radio 3 in November 2018.[6]
