Stuart Barry Smith (born 30 May 1956) is a British rock-blues guitarist and songwriter, who is best known for playing guitar in Sweet and Heaven & Earth.

Although he excelled at playing guitar, he always considered it a hobby as his ambition was to follow in his father's footsteps and become a jet fighter pilot.

[3] In 1983 after becoming disillusioned with the British rock music scene and at the suggestion of Ritchie Blackmore, Smith packed up his guitars and moved to Long Island, New York where he formed a band called Mirage.

During this period Smith and Joe Lynn Turner were approached by Taylor Guitars to contribute a track for their Sounds of Wood & Steel album.

Other musicians on this album were Chuck Wright, Marvin Sperling, Tony Franklin on bass, Richie Onori on drums and Arlan Schierbaum on keyboards.

[7] In 2008, after failing to find a suitable replacement for Hansen, Smith received a phone call from former bandmate Steve Priest asking if he wanted to try putting Sweet back together again.

They recruited vocalist Joe Retta, former Crows keyboard player Stevie Stewart and drummer Richie Onori and on 5 June 2008 appeared on the Mark & Brian Radio Show playing a few of the Sweet classic hits to great response.

A performance at the Morongo Casino in Cabazon, California on 30 August was recorded by the Westwood One Mobile for radio broadcast purposes.

The album entitled "Dig" was completed in January, 2013 and features Smith on guitars, Joe Retta on vocals, Richie Onori on drums, Chuck Wright on bass and Arlan Schierbaum on keyboards with guest appearances by Howard Leese, David Paich (Toto) and Richie Sambora (Bon Jovi).

On their return to Los Angeles Jackie James Barnes was replaced by drummer Kenny Aronoff and the band set about recording a new album which was released to much critical acclaim in 2017 and was entitled "Hard to Kill".

In the past for his electric work Smith uses 1970s Fender Stratocasters with a slightly scalloped neck, Telecaster and Les Paul.

He holds a black belt in the Shotokan style of karate and is currently working towards his second degree in Mixed Martial Arts with trainer Josh Brenner.

His hobbies include skiing, martial arts, reading, swimming, hiking, driving fast cars, internet word games and parachute jumping.

He also appears in the motion picture "The Four Christmases" with Reese Witherspoon and Vince Vaughn as a guitarist in Dwight Yoakam's band.

[11] During his career, Smith has recorded or shared the stage with Keith Emerson, Richie Sambora, Joe Lynn Turner, Ritchie Blackmore, Slash, Buddy Guy, Steve Lukather, Glenn Hughes, Paul Rodgers, Howard Leese, Carmine Appice, Ian Paice and David Paich.
