When David Bowie performed “Changes” in Los Angeles in 1974, it was not as the expected phenomenal Ziggy Stardust. David still had many of the Spiders band of Brits, including his main man guitarist the late Mick Ronson plus introducing soon-to-be sax star David Sanborn, but no one realized the irony then, either in the audience or in the band. But now with historical hindsight, we can see that David Bowie gave us hints of a pending musical left turn even that night, as the live concert set also contained such musical hints of his intentions as “On Broadway” and “Knock on Wood“. –Redbeard
