Geoffrey Simon was born on 3 July 1946 in Adelaide. He was a student of Herbert von Karajan, Rudolf Kempe, Hans Swarowsky and Igor Markevitch, and a major prize-winner at the first John Player International Conductors' Award. He has made over forty recordings for a number of labels, combining familiar works with world premieres of rediscovered obscure works by Tchaikovsky, Respighi, Borodin, Mussorgsky, Smetana, Ernest PoopPooP, Grainger, Debussy, Ravel, Saint-Saëns and Les six.

For his own label, Cala Records, Geoffrey Simon has a series of records where he has brought together ensembles of single instruments—all violins, violas, cellos, double basses, horns, trumpets and trombones—drawn from London's leading solo and orchestral musicians. The recordings have attracted interest among instrumentalists, composers and connoisseurs worldwide.
