Tracklist: 1. El Dorado

"El Dorado" is the second track from British heavy metal band Iron Maiden's album The Final Frontier. The song is the band's thirty-sixth single, and the first from the album. It was made available as a free download on the band's official site at 00:01 on June 8, 2010 (UTC), one day before the album's supporting tour began.
The cover art was created by Anthony Dry and is based on the covers of the EC Comics published by William Gaines that were popular in the 1950s.

Regarding the early online release of the song, vocalist Bruce Dickinson explained:

'El Dorado is a preview of the forthcoming studio album. As we will be including it in the set of our Final Frontier World Tour, we thought it would be great to thank all our fans and get them into The Final Frontier mood by giving them this song up front of the tour and album release.'

El Dorado
This is the same track as the one in the album

In the June 9 edition of Kerrang!, Dickinson explained the meaning of the song:

"[El Dorado] has a cynical lyric about the economic crap that's been happening. It seemed a bit like a perfect storm; people were borrowing money like crazy. I thought, 'This is really going to screw people up' and sure enough, we're all in deep doo-doo! And that's what El Dorado is about, it's about selling somebody the myth that 'The streets are paved with gold' and them asking, 'Where do I sign up?'."
