A recording engineer and record producer. He worked, in hardware, for EMI, but soon became an employee at their Abbey Road studios, where he assisted on The Beatles' Get Back (later to become Let it Be) and Abbey Road. Post-Beatles, he engineered/produced early Paul McCartney solo stuff and Wings LPs; he also helped The Hollies achieve a comeback/makeover for the 70s, when Graham Nash's departure should have consigned them to the nostalgia circuit.

His work on Pink Floyd's Atom Heart Mother led to his famous gig on Dark Side of the Moon, where he provided much of its painstaking sonic minutiae. That led, in turn, to providing the "Parsons Sound" to other mainstream rock projex - some OK, like Steve Harley and Cockney Rebel, or Pilot's "Magic"; some defined the awfulness of the 70s - Al Stewart's "Year of the Cat", or the American soft rock band Ambrosia.

With Eric Woolfson, he formed the Alan Parsons Project, a brand name for a "group" of session players; LPs include an Edgar Allan Poe set (Tales of Mystery and Imagination) and I, Robot. His fame - different from the showbiz svengalis who gained auteurhood - helped usher in today's Shinola Age, where engineers and techies are often more important than musicians, and "good music" means an impeccable aural sheen that masks an underlying dearth.
