Born in South Wales, Simon Wallace studied music at University College Oxford before going on to a varied international career as a composer, pianist and musical director. 

In 1980 he met film and TV composer Simon Brint establishing a writing partnership that continued until Brint’s death in 2011.  Over the years they wrote and produced music for some of Britain’s most popular television shows including: ‘Absolutely Fabulous’, ‘Murder Most Horrid’, ‘French and Saunders’, ‘The Ruby Wax Show’,  ‘The All New Alexie Sayle Show’, ‘Coupling’, ‘The Ben Elton Show’, ‘A Bit of Fry and Laurie’, ‘The Lenny Henry Show’ and many others.
 
He worked with lyricist and beat generation survivor Fran Landesman from 1994 till her death in 2011, writing songs that continue to be performed and recorded by singers on both sides of the Atlantic. The Observer newspaper once called them ‘one of the finest songwriting partnerships alive’.

His concert works include two symphonies commissioned by the Bangkok Symphony Orchestra for Thai state occasions.

Simon is a familiar face on the London jazz scene, appearing regularly at Ronnie Scotts Club, the 606 Club and the Vortex with some of Britain’s finest musicians. In 2013 he toured UK and Australia with singer Barb Jungr and is currently in various stages of producing albums for Barb Jungr, Pete Atkin, and Sarah Moule
