Born in 1985 in Hereford, UK, Garreth moved with his family to Wales at the age of 8. He began taking piano lessons aged 6, passing with distinction all but one of the ABRSM Piano Grade 1-8.
He studied Music at St Edmund Hall, University of Oxford under the supervision of Dr Roger Allen, a Wagner and analysis specialist. He wrote a dissertation on representations of sexuality in the operas of Benjamin Britten, supervised by the award-winning musicologist Professor Laurence Dreyfus. He sang in the St Peter's College choir and was awarded a choral scholarship for the St Edmund Hall college choir.
After leaving university he taught piano for a few years, then worked for the Youth Hostels Association, travelling the UK and abroad and working with young people. He backpacked up the west coast of the US and Canada while volunteering on organic farms.
In 2014 he moved to Frankfurt am Main Germany where he set up a piano teaching business and began exploring his interest in composition with the support of his artist partner, Anna Salzmann, a frequent collaborator. He released his crowd-funded debut album, Coping Mechanism, in early 2016. This album dealt with the loss of his mother to suicide, a topic he wrote about for Huffington Post UK. Between September 2016 and June 2017 he released a series of EPs on the acclaimed contemporary music label, 1631 Recordings, later released as the compilation album Another Turn.
In 2018 he moved to a new home in Harheim, Frankfurt, where he teaches piano lessons, composes music, and edits the contemporary piano sheet music project, Upright.
