I just started listening to Fahey, too. eMusic has a pretty good selection and I downloaded "Transfiguration of Blind Joe Death" and "God, Time and Causality". Fascinating music. I never gave him a chance before, but the variety of music he pours into his songs is astounding.
I'm thinking I will next get "Legend of Blind Joe Death", "Dance of Death & Other Plantation Favorites" and "Live in Tasmania".
I was a Loe Kottke fan ... WAY back. Started with "Mudlark" and picked up most of his Capitol albums through "Chewing Pine". Started slowing down on him when he switched to Chrysalis. Haven't listened to any of them in a long time, but great stuff.
