Were a British rock band active between 1975 and 1990, whose core membership consisted of Alan Parsons and Eric Woolfson. They were accompanied by a varying number of session musicians and some relatively consistent session players such as guitarist Ian Bairnson, arranger Andrew Powell, bassist and vocalist David Paton, drummer Stuart Elliott, and vocalists Lenny Zakatek and Chris Rainbow. Parsons was an audio engineer and producer by profession, but also a musician and a composer. A songwriter by profession, Woolfson was also a composer, a pianist, and a singer. Almost all the songs on the Project's albums are credited to "Woolfson/Parsons".
