In 1976 he formed Foreigner with Ian McDonald and recruited vocalist Lou Gramm. Jones co-produced all of the group's albums and co-wrote most of their songs with Gramm. Jones wrote the band's most successful single, "I Want to Know What Love Is". Tensions developed within the band during the early 1980s and were attributed to a difference in musical taste between Gramm, who favoured a more hard-edged rock, as opposed to Jones' interest in synthesisers. Gramm left the band in 1989 but returned in 1991. Also in 1989, Jones released his only solo album titled Mick Jones on the Atlantic Records label. Jones is the only person to play on every Foreigner album.
He was married to socialite/writer Ann Dexter-Jones, mother of Mark, Samantha and Charlotte Ronson. Ann and Mick have two children, Annabelle and Alexander Dexter-Jones. Married for nearly 25 years, in 2007 Jones and Dexter-Jones divorced. He also has two sons, from prior relationships, Roman, partner in Miami’s largest nightclub group, The Opium Group , and Christopher Jones.
