Mick Jagger got a call from his label recently with some news: While working on a reissue of the Rolling Stones’ 1973 album Goats Head Soup, the crew found some unreleased tracks. “I remember thinking, ‘Oh, no,’” Jagger says. “Unreleased tracks, to me that always means a lot of work. It’s like, ‘Things that you didn’t like and didn’t finish!’”

Jagger’s mind changed when he heard the music. “Actually, it’s not bad at all,” he says. Soon, isolating at his home in the European countryside, he wrote new lyrics to “All the Rage,” a rocker he’d started writing 47 years earlier. “You finish [tracks] like you would if you recorded them last week,” says Jagger. “ ‘Where are my maracas? Surely I must have my maracas around here.’”
