Please note that The Time Machine, On Air and Try Anything Once are not by The Alan Parson Project, and should be filed under the Alan Parsons artist (the new name of the project after Eric Woolfson's departure).
The Alan Parsons Project were a British progressive rock band, active between 1975 and 1990, consisting of Alan Parsons and Eric Woolfson surrounded by a varying number of session musicians and some relatively consistent band members such as guitarist Ian Bairnson, bassist and vocalist David Paton, drummer Stuart Elliott, and vocalist Lenny Zakatek.
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. Almost all songs on the band's albums are credited to "Parsons/Woolfson".
