John Aloysius Fahey was an American fingerstyle guitarist and composer who played the steel-string acoustic guitar as a solo instrument. His style has been enormously influential and has been described as the foundation of the genre of American primitive guitar, a term borrowed from painting and referring mainly to the self-taught nature of the music and its minimalist style. Fahey borrowed from the folk and blues traditions in American roots music, having compiled many forgotten early recordings in these genres. He would later incorporate 20th-century classical, Portuguese, Brazilian, and Indian influences into his work.
