I grew up really close to the Appalachian Trail. I love any and all Bluegrass singers. I see bluegrass as “Hillbilly Punk”. I also love anything Americana, from Rockabilly, to Folk, Early Blues, etc. Tons of rock and pop…..
As far as more modern singers, here’s a short list:
Ben Schneider (Favorite song last year by Lord Huron)
Amy Winehouse (I think was so very special)
So many others, I'm overwhelmed and can't do this list just. But Jesus, when you try to sing you immediately understand how important the human voice is and how having a great voice is such a fine instrument. I love the singers who aren't technically great singers but who are so expressive and unique - they prove that if you put your heart and soul into it, with practice you can be at least decent.
I'm in awe of so many great singers.
