After leaving the Sex Pistols, Matlock went on to form the Rich Kids, with himself as bass guitarist and singer, Midge Ure (guitarist, singer and keyboard player), Steve New (guitarist and singer) and Rusty Egan (drummer). They released three singles and one album entitled Ghosts Of Princes in Towers.
During this time, Matlock and New would play with Sid Vicious along with Rat Scabies in the one-off band The Vicious White Kids as part of a benefit performance in London, to help pay for Sid’s travel expenses back to America.
After The Rich Kids, Matlock would go on to form the short-lived Spectres, and then Hot Club. Prior to this Matlock toured Europe and North America with Iggy Pop and played bass and co-wrote material for his album Soldier.
In 1996, Matlock recorded and released his first solo album Who's He Think He Is When He's at Home? on Creation Records. However, the album’s release was overshadowed by Matlock rejoining the original Sex Pistols members for the first of their many reunion tours (1996, 2002, 2003, 2007 and 2008).
Beginning in the early ‘00s, Matlock would then assemble many short-lived groups including The Philistines, Dead Men Walking (feat. Mike Peters of The Alarm, Kirk Brandon of Theatre of Hate, and Pete Wylie of Wah!), and Slinky Vagabond (feat. Earl Slick, and Clem Burke).
In November 2006, the Sex Pistols were inducted to the Rock and Roll Hall of Fame.
In January 2010, Glen Matlock reformed The Rich Kids for a one-off benefit concert in aid of ailing Steve New. He was joined on stage by original members Rusty Eagan, and Midge Ure, as well as Mick Jones of The Clash, and Gary Kemp from Spandau Ballet. New would later die of cancer on 24 May 2010.
That same year, Matlock was asked to join a reformed Faces, and then in April 2011, he stood in on bass for Primal Scream at the Japan Tsunami appeal concert at Brixton Academy in London.
In late 2011, The International Swingers, a band comprising Matlock, Clem Burke, James Stevenson and Gary Twinn, was formed. The band, based in Los Angeles, toured Australia and the USA, and released a self-titled album in 2015.
In 2012, Matlock made his acting debut in British drama film The Paddy Lincoln Gang, performing a scene at a live Faces concert.
In 2017, Matlock joined a touring punk supergroup L.A.M.F. featuring Heartbreakers member Walter Lure, Clem Burke of Blondie, and Social Distortion's Mike Ness to pay tribute to the 40th Anniversary of Johnny Thunders & the Heartbreakers‘ classic LP, 1977’s L.A.M.F.
In 2018, Matlock released the critically acclaimed solo album Good To Go. A more stripped back, and almost rockabilly-styled album featuring legendary guitarist Earl Slick (David Bowie / John Lennon) and drummer Slim Jim Phantom (Stray Cats). The track “Keep On Pushing,” from the album was deemed “Best Song In The Universe Ever” on Little Steven’s Underground Garage radio show (Sirius XM).
In the summer of 2022, FX / Disney+ released the Danny Boyle directed Sex Pistols’ drama series Pistol (based on the Steve Jones autobiography ‘Lonely Boy’). Matlock was portrayed by actor Christian Lees in the series.
