Chris Willman Senior Music Writer and Chief Music Critic Ringo’s rotogravure is back, as it were, with a new EP, “Crooked Boy,” that will delight fans who’ve wanted a real rock record that was as steady as his backbeat. Linda Perry wrote and produced all four songs for this, the latest in a series of EPs that Ringo Starr began recording during the pandemic and is keeping on with well into the 2020s. He’s not married to the short-form format, though.
