Last saturday we've been at the Deep Purple concert here in Stuttgart in the Schleyerhalle. The Schleyerhalle was nearly sold out. After Gotthard as opener (they played 1:15h), Deep Purple started fast and furious with some tracks that I did not know (probably some newish :-) stuff).
But there have been enough 'classics' too and it was a great concert again. Don Airey is a good replacement for John Lord, but I missed the Organ-Guitar question and answer game, that John Lord and Richie Blackmoore were doing.
Deep Purple played 1:30h and then again 30 minutes.
It was a great concert and I would go there again.
