My epiphany is that I have become a folk music heretic:
I no longer care to hear Woody Guthrie Songs, either sung by him or others. After nearly 60 years it has grown tiresome to me. The sole exception is "The Ballad of Tom Joad" which I think is a brilliant 'cliff notes' of a masterful novel;
I no longer can listen to more than a couple of Bluegrass pieces at a sitting;
Never liked Bob Dylan's performances of his music. Like many others' performances though;
Never liked James Taylor (his music, not him), as I've often said at Mudcat;
Love acoustic blues, hate electric (often too dissonant for these old ears);
Loved Clancys, Rovers Irish music, but not so keen on today's Celtic;
I've come to appreciate JJ Niles. Even if some of his songs aren't 'authentic', they sound authentic.
I guess that's heretical enough.
