BB King is the most facile and appealing blues guitarist I know. Live at the Regal sets the standard for blues recordings.
Still, it’s amazing to see the 81 year old BB King, not that good at walking, play the guitar so fluidly, and lead the band and big crowd so ably.
Eric Clapton is right to stay in the shadows. This isn’t a great tune, but it certainly shows how great a player and performer BB King was.
