Buckingham is the first to agree that his career supports the axiom that personal crisis makes good art. Fleetwood Mac’s success peaked with Rumours, whose songs, such as Buckingham’s "Go Your Own Way," were inspired by the disintegrating relationships of John and Christine McVie and of Buckingham and Stevie Nicks. And Go Insane is Buckingham’s strongest work since then. But it’s not exactly a consolation. Lindsey’s voice takes on a note of wistful regret when he reflects on how "Stevie and I have such similar voices. We got to where we could harmonize so tight. We don’t do that a lot anymore-for obvious reasons."
