In a new interview with Planet Rock Magazine at MusicWeek.com Jimmy Page says...
“I can't give the game away, but there's a recording that’s another multi-track that we'll release,” said Page. “It's so different to all the other things that are out there. It's another view compared to How The West Was Won or The Song Remains The Same. I'm looking forward to people hearing that. There's a lot of stuff to come out, a number of releases. I'd like to say that they'll be coming out over the next 10 years. There's more to come for sure.”
