Gareth Koch was born in Milan in 1962, and began learning flamenco guitar at age twelve in Spain. Upon returning to Australia in 1976 he began a tumultuous love affair with rock and roll – an encounter from which he has never fully recovered.Gareth completed his undergraduate study in classical guitar at the Sydney Conservatorium of Music before winning post-graduate scholarships to both the Royal Madrid Conservatorium and the Academy of Music in Vienna. He holds a PhD in Music and his thesis explored the nature of creativity and the workings of the unconsciousmind during the act of creation.Gareth Koch has performed extensively throughout the world in a career encompassing flamenco, classical and world music styles. He has enjoyed an immensely varied career, having collaborated with some of Europe’s finest contemporary ensembles, theatres and flamenco dance companies. On reviewing one of his CDs, Britain’s Classical Guitar Magazine stated: “This is possibly the best CD I have ever reviewed.”
In 2002 Gareth became a founding member of Saffire: The Australian Guitar Quartet. Comprising the talents of Karin Schaupp, Leonard Grigoryan, and Slava Grigoryan the ensemble became a runaway success on the Australian music scene. Saffire’s debut album soared to number one in the Australian Classical Music charts and in 2003 won an ARIA for Best Classical Album. The quartet has toured Australia, Europe, and the USA and recently performed at the World Expo in Japan and the Hong Kong Arts Festival.
