Clarke was born in Broadstairs to a chemist father (who played in the National Youth Orchestra of Great Britain) and a mother who gave private music lessons in cello and piano.
He continued part-time studies at Guildhall whilst giving private lessons and performing with his rock band.
Along with Clare Southworth, Clarke led the Woldingham International Summer School for many years.
He has since performed as a featured guest soloist at major conventions in Italy, Brazil, Slovenia, Hungary, Netherlands and numerous times for the British Flute Society (BFS) and for the NFA.
His composing makes much use of extended techniques – jet whistles, timbral trills, alternative fingerings, and simultaneous singing and playing.
