She started her career as a session singer, and sang backup on several of Phil Spector's recordings, including The Righteous Brothers' "You've Lost That Loving Feeling" and The Ronettes' "Be My Baby". She rose to prominence in 1965 as one half of the pop/rock duo Sonny & Cher. Subsequently she established herself as a solo recording artist and is now one of the biggest-selling artists of all time.
Her biggest-selling single was "Believe", released in 1998. It was also the first Xenomania-written number one single.
The starting point for "Believe" was a song written by Brian Higgins, Matt Gray, Stuart McLennen and Tim Powell. After writing his first top five hit (Dannii Minogue's "All I Wanna Do"), Brian Higgins was asked if he "had any songs for Cher". He came up with "Believe". Higgins has said that when the song was initially written he was into The Stone Roses and Madchester: "that very British scene helped influence the writing of the song."
Higgins told in an interview that he missed out on the chance to produce "Believe" because he was too embarrassed to invite Cher to his home (a flat above a shop, which he claims "looked like where Top Cat lived") as it "didn't have a helipad". "There was no way I could have made a version as good as Brian Rawling did at the time. I certainly wouldn't have thought of the Vocoder...", he said.
"Believe" was the first commercial recording to feature the Auto-tune software used as a deliberate creative effect. Its producers first claimed that they used a vocoder, but they later admitted that they submitted Cher's vocals through the Auto-tune effect.
In February 2002 Cher released Believe's follow-up: Living Proof. Brian Higgins co-produced and co-wrote one song on the European version of the album ("You Take It All").
