"In Through the Out Door" is the eighth studio album by the British rock band Led Zeppelin. Released in 1979, this was the final album of entirely new material by the band released before the death of drummer John Bonham in 1980, marking the end of the group.
In contrast to prior albums, most of the album's material was composed by band members Robert Plant and John Paul Jones. This was largely due to the temporary deterioration of the personal lives of guitarists Jimmy Page and John Bonham around the time of the recording. The album reflected a change in the band's sound towards more polished and atmospheric songs, showing heavy influences of synthesizers thanks to Jones's experimentation.
The album was a commercial success, and it reached the number one position on Billboard's album charts. Popular tracks from the album include "In the Evening," "Fool in the Rain," and "All My Love." It was certified six times platinum by the Recording Industry Association of America in 1997, for sales exceeding six million copies.
Fun fact: The title 'In Through the Out Door' is an English idiom for achieving a difficult task by unusual or roundabout methods. It reflected the struggles the band was going through during the recording of this album. The record’s sleeve was uniquely designed by Hipgnosis and featured six different potential front covers.
