Peter Walker (born 1938) is an American folk guitarist, known for his skillful performances that blend Indian classical and Spanish flamenco music traditions.
He is now regarded as a prominent figure in the company of established American finger-pickers such as Sandy Bull, John Fahey, Robbie Basho and Leo Kottke.
From his base in Cambridge, he continued to travel extensively for 5 years, doing musical research in Mexico, North Africa, Algeria, Morocco, and Spain, often comparing notes with his friend and peer Sandy Bull.
He committed himself to tour and public performance from 1965 onward, becoming a fixture of the Greenwich Village folk scene of the mid-60s (during which period he became particularly close to Sandy Bull, Karen Dalton, Monty Dunn, Bruce Langhorne, Bob Gibson, Tim Hardin, and Fred Neil).
In 2000, he returned to Spain and made several trips each year, living in Romani communities, studying in Granada, and playing lead guitar at Casa Anselma in Seville.
