10cc are genuine oddballs who came of age in an era rife with eccentrics: pop pranksters and studio perfectionists who often seemed to play for their own amusement. They began their '70s run on the British charts with the oldies pastiche "Donna" and ended it with the reggae sendup "Dreadlock Holiday" -- 10cc nevertheless created two American soft rock perennials in "I'm Not in Love" and "The Things We Do for Love."The core of 10cc lies in the partnership between Eric Stewart and Graham Gouldman, two British Invasion veterans who initially played together in the Mindbenders, the Manchester group who had a hit in 1965 with "A Groovy Kind of Love." Various 10cc reissues and anthologies have been released, including a 30th anniversary box set in 2002 and a limited-edition 40th anniversary set in 2012 called Tenology. Another box set, Before, During and After: The Story of 10cc, arrived in 2017, with the comprehensive 14-CD box 20 Years seeing release at the beginning of 2024.
