JJ Cale passed away last Friday. I'll bet many who read this have never heard of him, aside from possibly knowing that he wrote "Cocaine", "After Midnight", and "Call Me the Breeze", songs made famous by Eric Clapton and Lynyrd Skynyrd, respectively.
JJ was a primo guitarist who was greatly admired by peers such as Neil Young. Some say Cale was so laid back he almost wasn't there. His voice, a quiet rough quality, perfect for gritty tales. If you dig bluesy, folksy, jazzy grooves, you should check out his catalogue.
