 A large part of Campbell's early career was spent as a clarinetist in the field of contemporary music as a member of Sir Peter Maxwell Davies' chamber ensemble, 'The Fires of London' also playing regularly with the London Sinfonietta, Endymion, and Lontano, but over the past twenty years David Campbell has developed the solo and chamber music strands of his career, performing in over forty countries with leading orchestras and ensembles.His repertoire is wide-ranging but he still champions new works, many of which have been written for him.The most recent were a new concerto 'River of Crystal Light' by Peter Lieuwen, which he played and recorded in the Texas Festival in June 2005 and a clarinet quintet, 'The Sun and the Moon' by Michael Stimpson which received its premiere in Aberystwyth with the RTÉ Vanbrugh Quartet in July 2005.
