RIP, Johnny Cash. As great and important as your music is, your legacy is greater than that. You were the man who brought Appalachian darkness to rock music, and gave us the literary rock song. You were the Man in Black, the visible symbol of conscience in country. You were a funny, conflicted man, but you lived your life on your terms. You were the spiritual grandfather of anyone who passionately loves their music served up with a heaping dose of bitterness and aching regret. I'm wearing black for you today.
