Legendary Beatles' engineer Geoff Emerick has died aged 72 following a heart attack.

He first worked with The Fab Four in 1963 as a tape op and within three years - and aged just 20 - Emerick was promoted to engineer on The Beatles' seventh studio album, Revolver.

The story goes that John Lennon asked Emerick to make his voice sound like "the Dalai Lama singing on a mountain" on the song Tomorrow Never Knows, a comment Emerick enjoyed repeating.

Giles Martin, son of the late Beatles producer George Martin, described Emerick as "one of finest and most innovative engineers to have graced a recording studio . . . We have all been touched by the sounds he helped create on the greatest music ever recorded."

Midge Ure, whose band Ultravox worked with Emerick on their 1982 album Quartet, called him "a lovely, quiet, unassuming man who helped change the way music was produced".

As well as The Beatles, Emerick worked on various Paul McCartney solo albums, including Band on the Run, for which he won a Grammy.

Geoff Emerick also worked with the likes of Kate Bush, Elvis Costello, Art Garfunkel, Split Enz and Judy Garland. One of the best-known songs he engineered was Manfred Mann's huge hit Pretty Flamingo.
