His 1967 debut album reached the top 10 in the UK, and the album's title song "Matthew and Son" charted at number 2 on the UK Singles Chart. Stevens' albums Tea for the Tillerman (1970) and Teaser and the Firecat (1971) were both certified triple platinum in the US by the RIAA. His musical style consists of folk, pop, rock, and Islamic music.

Steven Georgiou, born on 21 July 1948 in the Marylebone area of London, was the youngest child of a Greek Cypriot father, Stavros Georgiou (1900-1978), and a Swedish mother, Ingrid Wickman. He had an older sister, Anita (b. 1937), and a brother, David Gordon. The family lived above the Moulin Rouge, a restaurant that his parents operated on the north end of Shaftesbury Avenue which was a short walk from Piccadilly Circus in the Soho theatre district of London. All family members worked in the restaurant. His parents divorced when he was about eight years old, but they continued to maintain the family restaurant and live above it. Although his father was Greek Orthodox and his mother was a Baptist, Georgiou was sent to St Joseph Roman Catholic Primary School, Macklin Street, which was closer to his father's business on Drury Lane. Georgiou developed an interest in piano at a fairly young age, eventually using the family baby grand piano to work out the chords, since no one else there played well enough to teach him. Inspired by the popularity of the Beatles, at 15 he extended his interest to the guitar, persuaded his father to pay PS8 for his first instrument, and began playing it and writing songs. He would escape at times from his family responsibilities to the rooftop above their home, and listen to the tunes of the musicals drifting from just around the corner from Denmark Street, which was then the centre of the British music industry. Stevens emphasised that the advent of West Side Story in particular affected him, giving him a "different view of life". With interests in both art and music, he and his mother moved to Gavle, Sweden, where he attended primary school (Solangsskolan) and started developing his drawing skills after being influenced by his uncle Hugo Wickman, a painter. They subsequently returned to England. He attended other local West End schools, where he says he was constantly in trouble, and did poorly in everything but art. He was called "the artist boy" and mentions that "I was beat up, but I was noticed". He went on to take a one-year course of study at Hammersmith School of Art, as he considered a career as a cartoonist. Though he enjoyed art (his later record albums would feature his original artwork on his album covers), he wanted to establish a musical career and began to perform originally under the stage name "Steve Adams" in 1965 while at Hammersmith. At that point, his goal was to become a songwriter. As well as the Beatles, other musicians who influenced him were the Kinks, Bob Dylan, Nina Simone, blues artists Lead Belly and Muddy Waters, Biff Rose (particularly Rose's first album), Leo Kottke, and Paul Simon. He also wanted to emulate composers who wrote musicals, like Ira Gershwin and Leonard Bernstein. In 1965 he signed a publishing deal with Ardmore & Beechwood and recorded several demos, including "The First Cut Is the Deepest".
