Robin Duncan Harry Williamson (born 24 November 1943) is a Scottish multi-instrumentalist, singer, songwriter, and storyteller who was a founding member of the Incredible String Band.

Williamson lived in the Fairmilehead area of Edinburgh and attended George Watson's College before leaving at the age of 15 to become a professional musician.

[1] By 1965 he had returned to Edinburgh and formed a duo with Clive Palmer,[2] specializing in fiddle and banjo arrangements of traditional Scottish and Irish songs.

After the band split up in 1974, he began living in Los Angeles and, for a while, turned his attention to writing, co-writing an espionage novel, The Glory Trap.

They toured extensively for three years throughout the US, Canada, and Europe, and released three albums: Journey's Edge, American Stonehenge, and A Glint at the Kindling.

Williamson resumed his solo career on record with a series of albums for ECM: The Seed-at-Zero (2000), Skirting the River Road (2002), The Iron Stone (2006),[6] and Trusting in the Rising Light (2014).
