Plant announced via Facebook that a new album is "almost complete." Meanwhile, a number of performances seem to have been leaked, although none are confirmed by the singer himself. Here's the dates rumoured/leaked so far, via ledZeppelinNews (note: Tickets for the Germany shows are already on sale.)
June 12: Bergen, NorwayLast year at about this time, Plant said he had two albums almost done, one by the Sensational Space Shifters and one by the Band of Joy, recorded at Buddy Miller's home studio. There is no word on whether Plant and the Sensational Space Shifters' are finishing their original album, or have recorded a new one, but until there's an actual release date, I have to assume this album will no more see the light of day than those ones.
June 20: Moscow, Russia
June 25: Cork, Ireland
July 5: Cognac, France
July 16: Berlin, Germany
July 17: Dresden, Germany
And on the weekend of July 18-20, the Colours of Osrava Festival in Moravia, Czech Republic.
