Kenny Hall was an important figure in popularizing old time music in California. Being born blind, he had a unique ear for music and is said to have had over 1100 songs and tunes from the musical traditions of the U.S., England, Ireland, Portugal, Spain, and many other places.
He had a deep passion for nature and would frequently go on solitary hikes, snapping his fingers on either side of him and using echo-location to stay on the path.
Recordings of his music can be found on Slippery-Hill.com, along with source recordings of old time musicians from around the U.S. For more information about Kenny Hall, his music, and old time music in Fresno, CA, there is an interesting documentary about him called "I Hear What You See."
