The compilation was first released as a single CD album, which is the most commonly available form today.

It was later released with the original Tubular Bells, as a double CD album.

Other related releases include a 4-CD box set and a video album.

This compilation was released by Virgin after Oldfield had left the label, but includes "Sentinel" from Tubular Bells II courtesy of the Warner label.

Two of Oldfield's previous hits, "In Dulci Jubilo" and "Moonlight Shadow", were reissued alongside the album.
