Background: Curved Air are a pioneering English progressive rock group formed in 1970 by musicians from mixed artistic backgrounds, including classical, folk, and electronic sound. The resulting sound of the band was a mixture of progressive rock, folk rock, and fusion with classical elements. Along with High Tide and East of Eden, Curved Air were one of the first rock bands after It's a Beautiful Day and the United States of America to feature a violin. Curved Air released eight studio albums, the first three of which broke the UK Top 20, and had a hit single with "Back Street Luv" (1971) which reached number 4 in the UK Singles Chart.
Context: Having retained a good working relationship, Sonja Kristina and Mike Wedgwood formed a new band with Kirby Gregory (electric guitar), Eddie Jobson (keyboards, violin), and Jim Russell (drums). Jobson had come from a band called Fat Grapple, who had been one of Curved Air's support acts on tour. This new band played a much more conventional brand of rock than the former Curved Air, with almost none of the classical influences of that group. However, on the suggestion of manager Clifford Davis, they continued using the name Curved Air so as to give them a commercial leg up. Kristina later commented: What I wanted to do with the band at the time was get more of a rock edge to it, and Kirby's guitar playing really excited me - he was just really wild. And Jim was the same way, a very solid rock drummer. Mike and I really wanted to continue, and it was our manager Clifford Davis who said we would do a better business continuing to call the band Curved Air. So we kept the name and followed along the same pattern as before, as a writer's band. Everybody in the new band contributed material except for Jim Russell, who really wasn't a writer. Before it had mainly been Darryl and Francis, but I had managed to get some of my compositions in. The use of the Curved Air name was not enough, however. Whereas all three of the original Curved Air's albums had broken the UK top 20, the new band's sole album, Air Cut, failed to even chart. Due to artistic differences with Jobson, Kirby Gregory and Jim Russell both left the group to form Stretch. Warner Brothers realized that the current Curved Air was in essence not the same band they had signed, and so the remaining trio recorded a demo tape for the label. The demos failed to convince Warner Brothers, and they discontinued the contract. (These demos were later issued as part of the Lovechild record.) With no contract and only half a lineup, in summer 1973 Curved Air broke up. Jobson replaced Eno in Roxy Music, while Wedgwood joined Caravan.
