The song begins with a distinctive, wailing cry from vocalist Robert Plant and is built around a repeating, staccato Jimmy Page/John Paul Jones/John Bonham riff in the key of F# minor. There is a very faint count-off at the beginning of the track with lots of hiss which appears on the album version, but is trimmed from the single version. The hiss is feedback from an echo unit.[1]
"Immigrant Song" was written during Led Zeppelin's tour of Iceland, Bath and Germany in mid-1970. The opening date of this tour took place in Reykjavík, Iceland, which inspired Plant to write the song. As he explained:
We weren't being pompous ... We did come from the land of the ice and snow. We were guests of the Icelandic Government on a cultural mission. We were invited to play a concert in Reykjavik and the day before we arrived all the civil servants went on strike and the gig was going to be cancelled. The university prepared a concert hall for us and it was phenomenal. The response from the kids was remarkable and we had a great time. "Immigrant Song" was about that trip and it was the opening track on the album that was intended to be incredibly different.[2]
Just six days after Led Zeppelin's appearance in Reykjavik, the band performed the song for the first time on stage during the Bath Festival.[3]
The song's lyrics are written from the perspective of Vikings rowing west from Scandinavia in search of new lands. The lyrics make explicit reference to Viking conquests and the Old Norse religion (Fight the horde, sing and cry, Valhalla, I am coming!). In a 1970 radio interview, Plant jokingly recalled:
We went to Iceland, and it made you think of Vikings and big ships... and John Bonham's stomach... and bang, there it was - Immigrant Song![1]

Immigrant Song was first played live in Bath ... Bobby Darin had a hit with Splish Splash I Was Taking A Bath, though he's probably more widely known from the song Dream Lover ...
