When Chris Douridas launched Ground Zero, his new weekly radio show for KCRW in conjunction with AOL's Spinner.com, his first guest was none other than Madonna, who discussed the making of Music, perhaps the most ambitious album of her career. Madonna had just gave birth to her second child, so she did the interview over the phone from her home. Douridas also taps the insights of her various co-writers and producers: Mirwais, Guy Sigsworth, and brother-in-law Joe Henry.
