The Alan Parsons Project was a British progressive rock band, active between 1975 and 1990, consisting of Eric Woolfson and Alan Parsons surrounded by a varying number of session musicians and some relatively consistent band members such as guitarist Ian Bairnson.
Behind the revolving line-up and the regular sidemen, the true core of the Project was the duo of Parsons and Woolfson. Woolfson was a songwriter by profession, but also a composer and pianist. Parsons was a successful producer and accomplished engineer. Almost all songs on the band's albums are credited to "Woolfson/Parsons".
