Page and Plant recently sat down separately with the BBC's Rebecca Jones to talk about the reissues. The guitarist spent two-and-a-half years combing through the vaults, listening to hundreds of quarter-inch tapes before choosing the best material for the series.

Asked why he felt the need to be hands-on with this, Page explained, "I don't want to die and have somebody else do it. I'm authoritative about what was done in the first place."

Deluxe editions of the group's first three albums are the initial projects announced as part of an extensive reissue program that will see all nine of the band's studio albums reissued in chronological order, each remastered by Page.
