At the beginning of their career, Level 42 was squarely a jazz-funk fusion band, contemporaries of fellow Brit funk groups like Atmosfear, Light of the World, Incognito, and Beggar & Co. By the end of the '80s, however, the band —whose music was instantly recognizable from Mark King's thumb-slap bass technique and associate member Wally Badarou's synthesizer flourishes— crossed over to the point where they were often classified as sophisti-pop and dance-rock.
The band's commercial peak came with 1985's World Machine, but they continued to record and tour sporadically throughout the 90's and 2000's. Throughout this period, the band's lineup fluctuated, with King as the lone constant and his brother, guitarist Nathan King, on-board since 2001.
Level 42 released a studio album, Retroglide, in 2006. Four years later, the band celebrated its 30th anniversary with a special tour, as well as a box set, Living It Up, which included a disc of fresh acoustic versions recorded by Mark King and Mike Lindup.
