Here's a shout out to the amazing Johnny Cash! I grew up listening to his music because my mom sang his songs to us when we were knee-hi to a June bug. As an adult, I admired his songwriting talent and his unique voice. A country rocker from the get go.
Gotta mention that Joaquin Phoenix did a terrific job playing the Man in Black in Walk the Line (2005). Amazingly he sang the songs himself!
