I’ve got good news and bad news for Robert Plant fans.  The good news – a massive archive of unreleased music is out there waiting to be heard.  The bad news – you won’t hear any of it until Plant is six feet under. On a recent episode of his Digging Deep podcast, the 72-year-old Plant said he just went through his archives organizing everything.  He said “I told the kids that when I kick the bucket, open it to the public – free of charge”. The archive includes collaborations with everyone from Grace Jones to The Buggles – and a lot of what Plant calls “silly things”.
