Rolling Stone reports (via NME) that the new reissues will include the original albums remastered by guitarist Jimmy Page, as well as previously unheard audio from the band's archives including alternate mixes of "Rock and Roll," "Misty Mountain Hop "and "D'Yer Mak'er."
Due to release on October 28, both albums will be available to purchase as a single album or vinyl LP, a deluxe double LP, or as a digital download. Also released will be a super deluxe box set, which features the CDs, LPs, a download card and a special 80 page hardbound book. Last month, similar reissues of the band's first three studio albums were released.
In May, Page revealed that he was "fed up" with singer Robert Plant for delaying a potential band reunion. Led Zeppelin last played together in December 2007 at London's 02 Arena, but Plant has dismissed the possibility of another reunion any time soon.
"I was told last year that Robert Plant said he is doing nothing in 2014, and what do the other two guys think? Well, he knows what the other guys think. Everyone would love to play more concerts for the band. He's just playing games, and I'm fed up with it, to be honest with you. I don't sing, so I can't do much about it," said Page.
