Gareth Koch (born 6 April 1962) is an Australian classical guitarist and recording artist of German/Anglo-Irish/ Lithuanian heritage.
Gareth Koch was born in Milan to novelist Christopher Koch and Irene Vilnonis, a Conservatorium trained pianist. Gareth was raised in Sydney, Melbourne, Launceston and various European cities. Koch began to study guitar in Spain at the age of twelve. He made his recording debut in Vienna.
Koch studied music performance at the Sydney Conservatorium of Music at the University of Sydney, graduating with a Bachelor of Music degree in 1987. He subsequently won scholarships to complete postgraduate study in classical guitar at the Madrid Royal Conservatory, gaining a Diploma of Music, and at the University of Music and Performing Arts, Vienna. He later completed a PhD in Music at the University of Newcastle, with a thesis exploring the nature of creativity and the workings of the unconscious mind during the act of creation.
Following 10 years in Vienna, Koch was signed by Artworks Recorded Music in 1996 for whom he released several solo albums. Since then he has toured extensively in Europe, North America and Asia. He changed labels to ABC Classics Australia in 2003 and has subsequently released further solo albums. One of these was his controversial transcription of Carl Orff's Carmina Burana.
