William first came to international attention when he won the first prize, gold medal and Rosa Sabater prize at the Concurso Internacional de Piano in Jaen, Spain in 1984.
This was the first of many prizes at international level, which include the Busoni, Cleveland, Iturbi, and Scottish International Competitions. His London concerto debut with the Philharmonia Orchestra at St John’s Smith Square soon followed, and since then he has performed at major venues in cities worldwide.
Highlights include his Moscow and St Petersburg debuts under the auspices of the Sviatoslav Richter Foundation and critically acclaimed tours of Spain and France. As a chamber musician, William performs with ensembles such as the Brodsky Quartet, and the Guildhall Strings and has collaborated with the singers Steve Davislim and James Rutherford.
As well as recording for BBC Radio 3, William's performances have been broadcast on Classic FM, BBC television and on European and US radio and television. CD recordings are available on Olympia and Guild Records.
