Conversation so far:
What is the new curved air
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).
Were the new Curved Air more popular than the former Curved Air
Whereas all the original Curved Air's albums had broken the UK top 20, the new band's sole album, Air Cut, failed to chart.
Did the New Curved Air dissolve after the sole album, Air Cut, failed to chart??
Curved Air broke up so quietly that, by Sonja Kristina's recollections, most of the music press wrote off the band's absence as a sabbatical.
Is stretch the new name for the new curved air“
Due to artistic differences with Jobson, Kirby Gregory and Jim Russell both left the group to form Stretch.
What did the critics have to say about Stretch?
Stretch rose from the ashes of this debacle, and soon had a No. 16 hit single in November 1975
How did the demo do for new Curved air?
Sonja Kristina recorded a demo tape for Warner Brothers but they discontinued the contract. (These demos were later issued as part of the Lovechild record.)
Was Lovechild record a hit for the band new Curved Air?

Question: Have they been broken up since then
Self-contained rewrite: Has the band new Curved Air been broken up since Lovechild?
