B. B. King died late last night in Las Vegas. He was 89. He won 15 Grammy Awards. But more importantly, he left an incredible legacy and a canon of work that will continue to influence musicians for ages. I had a great moment once with BB, on the stage at Radio City Music Hall. There was a break during the taping of Martin Scorsese’s blues documentary. I was talking to Bonnie Raitt, and BB, who did not know who I was from a hole in the wall, motioned for me to get Bonnie’s attention. She came over, and he said, “I just want you know you’re the best slide guitarist I’ve ever heard.” Wow. Bonnie was startled and grateful. The King had bestowed this honor on her. And he was happy to do it. Now that BB is dead, let’s just sit back and remember his incredible gift.
