Alexis Mardas, also known as Magic Alex, was the head of The Beatles' Apple Electronics.
Mardas was introduced to John Lennon by Brian Jones. He was then temporarily hired in 1968 by the Beatles to build them a studio. Mardas promised them the world's first 72-track studio but the results were pathetic and unusable, having no soundproofing, no mixing desk, and no way to run the wiring between the control room and the studio. When he failed to deliver, The Beatles' Let It Be project had to be recorded with two 4-track recorders, borrowed from EMI.
Mardas was fired by Allen Klein in 1969. It later came out that his main electronic experience had been as a television repairman.
