"I've done my bit. Technology has moved on since the last set of remasters and you can hear the difference in these new versions. They're quite something," Page explains. "Obviously there's not that much material that we could add from the first two albums, but from Led Zeppelin III there is."

Alternative takes and outtakes are all apparently part of the releases. No date is scheduled yet � Page is renowned for his methodical approach � but there will be remastered Led Zeppelin out in 2014.
