Documentarian D.A. Pennebaker focuses his lens on a 1973 concert by David Bowie, who performs under the moniker Ziggy Stardust with his glam-rock backing band, the Spiders From Mars. While some backstage footage of the theatrical singer-songwriter is featured, the majority of the film is devoted to the music played onstage, which includes hits, album cuts and covers of Rolling Stones and Velvet Underground songs. Bowie also shocks fans by announcing his intention to drop the Stardust persona.
