Andrew McIan Fraser (3 July 1952 – 16 March 2015) was a British musician and songwriter, best known as the bassist and co-composer for the rock band Free, which he helped found in 1968 when he was 15.

Fraser was born in the Paddington area of Central London to a Barbadian/Guyanese father of mixed European and African ancestry, and an English mother.

By thirteen he was playing in East End, West Indian clubs and after being expelled from St Clement Danes Grammar School in 1968 at the age of 15, enrolled at Hammersmith College of Further Education.

[4] Shortly thereafter, upon receiving a telephone call from John Mayall who was looking for a bass player, Korner suggested Fraser; still only 15, he was now in a professional band and earning £50 a week, although it ultimately turned out to be a brief tenure.

[7] Free initially split in 1971, and Fraser formed a trio, Toby, with guitarist Adrian Fisher, and drummer Stan Speake.

After leaving Free, Fraser formed Sharks with vocalist Snips (later Baker Gurvitz Army), guitarist Chris Spedding and drummer Marty Simon.

At the time of the new album's release, Fraser was interviewed by Dmitry M. Epstein for the DME website and revealed: "To be quite honest, I never thought of myself as a bass-player.

[10] In early 2006, writing for Vintage Guitar magazine, Tom Guerra conducted a comprehensive interview with Fraser, covering his career, influences and instruments and, in April, Fraser responded to the revival of interest in his music by announcing two rare live shows at Southern California's Temecula Community Arts Theatre on 4 May.

The project includes a five-part documentary, narrated by British music show anchor-man Mark Radcliffe plus online and radio content.

"The documentary aims to explain the success of some of the greatest bands of the past 50 years, including the Who, the Police, the Doors, Bon Jovi and the Foo Fighters".

In mid-2013, Fraser played a supporting role as bassist in the band of protege Tobi Earnshaw for a short series of UK dates.
