From Roger on Twitter: "Best show of my solo career tonight in Leipzig incredible venue amazing audience. Finally I played like I know I can Danke!"
Update: Here's an interview (English translation here) Roger did while at the festival. (Thanks Schneeflocke)
And a bit of clarification from Roger: "Well if you can make any sense of that you are a better man than I! It wasnt an interview it was a conversation but his pass did say PRESS so I should have known better... and nobody fell asleep. Im not sure how a secret album would work? and no its nonsense!"
Update 2: Some photos from the show.
