John Christopher Williams AO OBE (born 24 April 1941) is an Australian virtuosic classical guitarist renowned for his ensemble playing as well as his interpretation and promotion of the modern classical guitar repertoire. In 1973, he shared a Grammy Award in the Best Chamber Music Performance category with fellow guitarist Julian Bream for Together (released in the US as Julian and John (Works by Lawes, Carulli, Alb niz, Granados)). Guitar historian Graham Wade has said that “John is perhaps the most technically accomplished guitarist the world has seen.”
