Led Zeppelin have hinted they may release more unheard material.
The band are due to release deluxe editions of their first three albums, 'Led Zeppelin', 'Led Zeppelin II' and 'Led Zeppelin III', on June 3, and now guitarist Jimmy Page has revealed he might put together compilations of rare songs in the future.
He teased in an interview with Rolling Stone magazine: ''There's certainly more things that can be done. But these reissues took a lot of time, and I don't want to start proposing another project, because it'll take me another six months or a year.''
Jimmy spent years scouring through the band's archives in a secret west London vault to find tracks that hadn't been heard by even the most hardcore of their fans, including a cover of 'Keys To The Highway' and versions of 'Immigrant Song' and 'Whole Lotta Love'.
He explained: ''I was pretty diligent with my detection work. I asked a guy that runs one of the fanzines if he'd heard any of this material before, and he told me hadn't. That was a good feeling.''
The group - also comprised of bassist John Paul Jones and singer Robert Plant - have launched an extensive reissue program of all nine of their studio albums in chronological order, each remastered by Jimmy.
However, they have ruled out all possibilities of a live Led Zeppelin show to coincide with the album releases.
