For fans of Led Zeppelin, there’s no such thing as too many remasterings and reswizzlings of those classic albums, and when a new series of reissues comes with the added bonus of previously unheard songs, it’s time to celebrate in an appropriately enormous fashion. 
 
 BBC News has clips of two of the songs that will accompany the release of the band’s first three albums, this June. There’s the blues standard “Keys to the Highway” from 1970, and a not-quite-finished run through “Whole Lotta Love,” both of which should serve as appetizers for the gigantic pile of songs—a rarities disc with each album—ranging from alternate takes and live performances, including an entire Paris gig from 1969, to work-in-progress ideas and the occasional lost gem. 
 
 Jimmy Page has spent the last couple of years putting the releases together from the band’s vault of recordings. And he told BBC News that the unvarnished version of a song like “Whole Lotta Love” made him aware of how much work the band put into the fine polish and extra guitars and vocals to really make it fly: “You realize just how important all of those additional layers and the filigree work is. 
 
 “There’s all manner of bells and whistles to make it the song ‘Whole Lotta Love’ as we all know it.” 
 
 That said, it’s not as if laying the songs bare has exposed an essential weakness in their sound: “It’s undeniable that we’re good,” he said. “The band was the real deal.” 
 
 For Robert Plant, it has been a slightly different experience, in that there are a lot of things he rather wishes he had done differently: “My enthusiasm sometimes got in the way of finesse. I listen to it and go, wow, why didn’t I shut up a bit? I kind of overcooked it.” 
 
 But his enthusiasm for the work still shines through: “It was a particularly prolific time, where we were learning about each other’s capabilities. 
 
 “Jimmy and I were just fooling around with the stuff that we would play at home. We were just trying things out. Nothing was premeditated.” 
 
 And he offers firm advice for any would-be listeners: “These things aren’t to study. They’re to turn up very loud and say, hey, once upon at time, everything was just as easy as this.”

 Legendary rock group Led Zeppelin have unveiled two previously unheard recordings ahead of the reissue of the band's first three albums in June. 
 
 The two tracks - blues classic Keys to the Highway, recorded in 1970, and an early version of the famous song Whole Lotta Love - are among dozens of tracks which the band will officially release alongside the reissues.

 The companion discs will feature alternative versions of songs, works in progress and live performances, all recorded at the time of the original albums. 
 
 The tracks, like hundreds of others, had been carefully catalogued but then locked away in the the band's archive for decades. 
 
 Guitarist Jimmy Page, 70, has spent two-and-a-half years combing through the vaults, listening to hundreds of quarter-inch tapes before choosing the best material.

 "I don't want to die and have somebody else do it," he says. "I'm authoritative about what was done in the first place." 
 
 Page says the new material "deserves to be heard" because "it's performance art".

 It will give fans the first chance to eavesdrop on some of the band's key recording sessions. 
 
 Keys to the Highway/Trouble in Mind, to appear on Led Zeppelin III, was recorded in 1970 at the Olympic Studios in Barnes in south-west London, about half an hour after Hats Off to (Roy) Harper. But it was never released. 
 
 "It was a particularly prolific time," says singer Robert Plant, "where we were learning about each other's capabilities. 
 
 "Jimmy and I were just fooling around with the stuff that we would play at home. We were just trying things out. Nothing was premeditated." 
 
 My enthusiasm sometimes got in the way of finesse Robert Plant on his early recordings 
 
 Led Zeppelin II features an early version of Whole Lotta Love, which many consider to be one of the greatest rock 'n' roll songs of all time. 
 
 There are significant differences between the two tracks. The original is missing the first chorus and middle section. New vocals appear on the finished version, as well as a slide guitar. 
 
 "You realise just how important all of those additional layers and the filigree work is," says Page. 
 
 "There's all manner of bells and whistles to make it the song Whole Lotta Love as we all know it." 
 
 Page says it's "reassuring" revisiting the songs after all this time. 
 
 "It's undeniable that we're good," he adds. "The band was the real deal." 
 
 But the inevitable passage of time has given Plant, who is now 65, a different perspective. 
 
 "My enthusiasm sometimes got in the way of finesse. I listen to it and go, wow, why didn't I shut up a bit?" he laughs. "I kind of overcooked it." 
 
 'Very loud' 
 
 Page promises "lots of surprises" on the three reissues, which are part of a plan to reissue all nine of the band's studio albums in chronological order. 
 
 But he has scotched rumours that there will be versions of songs featuring bass and keyboard player John Paul Jones on vocals. 
 
 For a band that broke up in 1980, following the death of the drummer John Bonham, interest in Led Zeppelin remains intense. 
 
 The surviving members reunited seven years ago for a concert at London's O2. But fans will be disappointed if they are hoping there will be another one. 
 
 Page says: "I'm sure people would love to hear it. I'm not the one to be asking, I don't sing." 
 
 Plant, however, is unequivocal. The chances of the band performing live again are, he says rolling his eyes, "zero". 
 
 So fans will have to content themselves with the reissued albums. And Robert Plant has one piece of advice for them. 
 
 "These things aren't to study. They're to turn up very loud and say, hey, once upon at time, everything was just as easy as this."
– Led Zeppelin is reissuing its first three albums in June, but ahead of that comes a little more love for fans. Actually, it's a "Whole Lotta Love" and "Keys to the Highway"—previously unreleased versions that Jimmy Page culled from the band's vault in a two-year labor of love. "I don't want to die and have somebody else do it," he tells the BBC, which has clips of the songs. "I'm authoritative about what was done in the first place," and the new music "deserves to be heard." "Keys to the Highway" was recorded in 1970, in what Robert Plant calls "a particularly prolific time where we were learning about each other's capabilities. Jimmy and I were just fooling around." The "Whole Lotta Love" track is an early version—missing some vocals, slide guitar, the middle section, and first chorus—which makes one "realize just how important all of those additional layers and the filigree work is" in the final track, Plant says. He adds a pretty frank assessment of his own skills at the time: "My enthusiasm sometimes got in the way of finesse. I listen to it and go, wow, why didn't I shut up a bit? I kind of overcooked it." He's equally blunt about any chance of a reunion: "Zero" chance, says he. Still, the new tracks alone are cause for celebration, writes Fraser McAlpine at the Anglophenia blog. "For fans of Led Zeppelin, there’s no such thing as too many remasterings and reswizzlings of those classic albums."
