Scott Walker, one of the most enigmatic and influential figures in rock history, has died at the age of 76.

The US star found fame as a teen idol in The Walker Brothers, scoring hits with The Sun Ain’t Gonna Shine Anymore and Make It Easy On Yourself.

But his dark baritone hinted at something deeper – and his darker, experimental solo albums tackled the complexities of love, sex and death.

Walker’s death was confirmed by his current record label, 4AD.

In a statement, they called the singer “one of the most revered innovators at the sharp end of creative music”.

Radiohead’s Thom Yorke was among those paying tribute, describing Walker as “a huge influence on Radiohead and myself, showing me how I could use my voice and words”.

Born Noel Scott Engel in Ohio, 1943, Walker initially pursued a career as an actor, before hooking up with John Maus and Gary Leeds to form the misleadingly-named Walker Brothers.

After a false start in the US, they relocated to England, where they caused a huge sensation, scoring number one hits with Make It Easy On Yourself and The Sun Ain’t Gonna Shine Anymore.

For a while, the band were as big as the Beatles, greeted by screaming fans everywhere they went.

“It was fantastic for the first couple of albums or so but it really wears you down,” Walker told the BBC’s Culture Show in 2006,

“Touring in those days was very primitive. It was really a lot of hard work. And you couldn’t find anything good to eat. The hours were unbelievable.

Orchestral pop

At the height of their fame in 1967, when Walker was still considered a heart-throb and a potential superstar, he called time on the band and ran away to a monastery on the Isle of Wight. Not, as rumour had it, because of a nervous breakdown, but to study Gregorian chant.

He remained disillusioned with the industry until his girlfriend introduced him to the music of Jacques Brel, whose literate, passionate torch songs inspired him to embark on a solo career.

Walker’s first four solo albums, Scott to Scott 4, juxtaposed lush, orchestral pop with dark existentialism; and his lyrics were frequently scattered with characters from society’s margins – prostitutes, transvestites, suicidal thinkers and even Joseph Stalin.

“He took music to a place that it hasn’t actually ever been since,” said musician Brian Eno who, like Jarvis Cocker and David Bowie, cites Walker as a key influence.

Amid falling sales, Walker staged a brief, largely unsuccessful reunion with the Brothers in the mid-70s; then used a lucrative deal with Virgin Records to pursue some of his most abstract musical ideas on 1984’s Climate of Hunter.

The record divided fans and critics – it was reputedly Virgin’s lowest-selling album of all time – and Walker bowed out of music and the public eye for almost a decade.

“A friend of mine says I’m not a recluse, I’m just low-key,” said the singer about his extended absence.

“Generally if I’ve got nothing to say, it’s pointless to be around.”
