Exposed was recorded at various locations across Europe during Oldfield's debut concert tour as a solo artist, following the release of his fourth studio album Incantations (1978). The album features Incantations and his debut album Tubular Bells (1973) performed in their entirety, plus Oldfield's 1979 non-album single "Guilty" as the encore.
Exposed was initially marketed as a restricted release with just 100,000 copies produced, but strong sales prompted Virgin Records to give the album a full release. It peaked at No. 16 on the UK Albums Chart and earned a silver certification from the British Phonographic Industry for selling 60,000 copies.
After undergoing Erhard Seminars Training in 1978, the formerly reclusive Mike Oldfield launched a Europe-wide tour with instrumental and choral ensemble to promote his fourth solo album, Incantations.
Initially during the tour the concerts were being recorded without the knowledge of the musicians, so that they could be paid less money, for just a performance and not a recording. The musicians found out, but the recordings went ahead and the album was produced.
The artwork is linked to the title, as it shows a frame of film containing a photo of Oldfield in a concert arena. Among the choir singers were members of the Queen's College, London choir. The all-female choir singers were selected strictly based on their looks.
Due primarily to costs associated with the numerous support singers and musicians, the tour made a net loss of half a million pounds.
The album was recorded using The Manor Studio's Mobile unit, and mixed at The Town House, London. The double vinyl album was released in 4 channel quadraphonic sound using the SQ Quadraphonic encoding system. This was one of the last quadraphonic albums released.
