Last November in London, Cat Power took the stage at Royal Albert Hall and delivered a song-for-song recreation of one of the most fabled and transformative live sets of all time. Held at the Manchester Free Trade Hall in May 1966—but long known as the “Royal Albert Hall Concert” due to a mislabeled bootleg—the original performance saw Bob Dylan switching from acoustic to electric midway through the show, drawing ire from an audience of folk purists and forever altering the course of rock-and-roll.
