Back in Black in 42 Days

Brian said the band recorded the entirety of 'Back In Black' shortly after he joined the band--in just six weeks: "It was probably the most magical time of my life."

The record made them international stars; before it's release, "everybody loved them but they were just breaking in America and everywhere [else]."

They've been brothers ever since: "We still travel together. We still share the same dressing room."
