John Christopher Williams is an Australian-born 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. Guitar historian Graham Wade has said that "John is perhaps the most technically accomplished guitarist the world has seen."

Julian Alexander Bream was an English classical guitarist and lutenist. Regarded as one of the most distinguished classical guitarists of the 20th century, he played a significant role in improving the public perception of the classical guitar as a respectable instrument. Over the course of a career that spanned more than half a century, Bream also helped revive interest in the lute.
