In Through the Out Door is the eighth and final studio album by the English rock band Led Zeppelin. It was recorded in three weeks in November and December 1978 at ABBA's Polar Studios in Stockholm, Sweden, and released by Swan Song Records on 15 August 1979.
 Unlike earlier Led Zeppelin albums, In Through the Out Door was dominated musically by John Paul Jones. It was the band's last studio release before they disbanded in December 1980 after the death of their drummer John Bonham three months earlier.
