Buddy Guy walked up to the Tiny Desk and reminded everyone exactly why he’s the last man standing among the architects of the blues, opening with “Damn Right, I’ve Got the Blues” and “Hoochie Coochie Man” before being joined by Miles Caton, his co-star from the 16-time Oscar-nominated film ‘Sinners’, for a playful, powerful exchange that captures the full arc of a musical tradition passing between generations, with the 9-time Grammy winner and Rock and Roll Hall of Famer wailing on his polka dot Stratocaster like a man who turns 90 this year and has absolutely nothing to prove and everything still left to play.
