Time Machine is the fifth studio album by guitarist Joe Satriani, released on October 26, 1993 through Relativity Records and reissued in 1998 through Epic Records. It is a double-disc compilation: the first disc contains a selection of new tracks, outtakes and unreleased studio recordings, while the second disc is composed of live recordings from 1988 and 1992.
The album's 1998 reissue contains detailed liner notes explaining the story behind the content of both discs. Five tracks were originally recorded during the sessions for The Extremist (1992): "Crazy", "Banana Mango II", "Thinking of You", "Speed of Light" (featured on the soundtrack to the 1993 film Super Mario Bros.) and "Baroque". Four other tracks were previously released on Satriani's 1984 self-titled EP: "Banana Mango", "Dreaming #11", "I Am Become Death" and "Saying Goodbye".
