David has played the keyboard (rather reluctantly to start with!) since he was 5 years old, but soon became very keen on it. Around the age of 15 he took up the organ and was able to have lessons on the organ of Rochester Cathedral under Gavin Williams and David Oldbury.

At university (University College London) whilst reading for a degree in Electronical and Electronic Engineering, David played the organ and sang in the University Church of Christ the King in Gordon Square, London WC1 under the musical directorship of Alan Wilson. There he played the organ in many of Britain's cathedrals for choral evensong, choral mattins and choral eucharists.

With Alan Wilson, David teamed up to form their Synthesizer Duo. They played concerts of popular classical music on 8 or more keyboards, gave master classes at the Royal School of Church Music, schools and other venues and were the first to use synthesizers in a worship context on BBC Radio 2 (Sunday Half Hour - 17th April 1988) and BBC Radio 4 (Daily Service - 20th October 1989). David authored the RSCM handbook 11: "Synthesisers in worship".
