From the 1975, The Original Soundtrack is an excellent example of the art-rock genre. Produced by 10cc for PolyGram, they are Queen-esque in sound and vocals with instrumental creativity tossed with a good dose of humorous lyrics. The Original Soundtrack showcases 10cc's sweet, yet ambitious, harmonies combined with layers of instruments, lots of adrenaline, and a bit of crooning in a Dean Martin/Freddie Mercury sort of way. One of the well-known songs on this recording is "I'm Not In Love" which spent three weeks at No. 2 on the chart.
