I find that it isn't wise to attempt to judge people on their public persona and even on the music they make. Because I've met so many people whose music I cannot stand and they're very nice. At the same time I've met people whose music I've loved and they're not the person you've invested all this emotion in.
I dabbled in things like Howlin' Wolf Cream and Led Zeppelin but when I heard Son House and Robert Johnson it blew my mind. It was something I'd been missing my whole life. That music made me discard everything else and just get down to the soul and honesty of the blues.
