After punk rock hit in the mid-70's, most veteran rockers took note of the 'back to basics' style and cut down on extended suites that took up entire sides of records.
But some bands appeared completely unfazed by punk . . . such as Sky.
Led by classical guitarist John Williams and comprised mostly of respected session musicians (electric guitarist Kevin Peek, bassist Herbie Flowers, and drummer Tristan Fry), Sky scored a hit straight away, with a 1979 self-titled release that managed to combine both classical music and rock.
The whole thing came off sounding like instrumental prog (largely thanks to synth player Francis Monkman).
