I was a rap/metal/alternative musical snob until the time I started working at a major bookstore chain's music department. We were allowed to take home the CDs that we played over the store PA. There was a 2-disc Doc Watson anthology in the pile, and I knew it sold at the store for a good price, so I figured I'd take it home and flip it for a few bucks at the local second-hand record shop (remember those?).
Thing is, I saw that the song titles included a few with the word "blues" in them... 'how bad could they be?' I thought.
I cued up the firs disc, and my musical life changed forever.
