Physical Graffiti is the sixth studio album by the English rock band Led Zeppelin, released as a double album on 24 February 1975 by their newly founded imprint label Swan Song Records.
 The band wrote and recorded eight new songs for the album at Headley Grange, which stretched the total time of the record beyond the typical length of a single LP, so the band decided to make "Physical Graffiti" a double album by including unreleased tracks from earlier recording sessions: one outtake from "Led Zeppelin III," three from "Led Zeppelin IV," and three from "Houses of the Holy", including the unused title track from the latter album.
"How Many More Times" is the ninth and final track on English rock band Led Zeppelin's 1969 debut album "Led Zeppelin".
 The song is credited in the album liner to Jimmy Page, John Paul Jones, and John Bonham, but Robert Plant was later added to the ASCAP credits.
The Led Zeppelin Deluxe Edition is a series of albums reissued by English rock group Led Zeppelin, distributed by Atlantic Records.
 It contains all nine of the original Led Zeppelin studio albums remastered from the original analog tapes.
 Along with the remastered albums, there is a companion disc with each album, consisting of previously unreleased audio tracks and alternate mixes of released tracks.
 Many of these are described as work-in-progress or alternate mixes made during the original production rather than new remixes generated to highlight discarded recording elements (as did the remixes made for "The Beatles Anthology").
 The first companion album consists of the 10 October 1969 concert in Paris.
 The albums were released in chronological order, each with inverted album covers.
"Immigrant Song" is a 1970 song by the English rock band Led Zeppelin.

 The song was included on their third studio album, "Led Zeppelin III", and was released as a single, which charted in several countries.
 Several live recordings have also been issued on Led Zeppelin concert albums and other artists have recorded renditions of the song.

 It has been described as the band's heaviest album.
