“It was well into the homestretch of the concert, but Mr. Young just kept going nonstop for 15 minutes. He played blues riffs and zigzag lead lines and nagging trills and manic tremolo crescendos, racing around and under and up and down the whole stage set to end up on an elevator platform in a shower of confetti. It was a show of stamina and of sheer, cantankerous rock ’n’ roll persistence.” Huzzah, dude.
