Sharing the format of its two predecessors - Tubular Bells and Hergest Ridge, Oldfield stays loyal to his conceptual roots in Ommadawn, but incorporates musical styles from a far greater range of influences including folk, Celtic, and middle eastern sounds. As a result, Oldfield channels greater scope for musical development, defining Ommadawn as a creative peak in Oldfield's wide-ranging career.
Composing for traditional Celtic instruments such as the uilleann pipes, Oldfield uses Ommadawn as an outlet for spiritual investigation as much as expert musicianship. A master of songcraft, Oldfield layers guitars, pipes, drums and vocals to create a masterpiece pumped full of ethereal mysticism and described by one critic as "the musical equivalent of astral projection". Says Oldfield "I do not feel I am musician. I don't know... I create sounds, that are reflections of my emotions."
