At Sweden Rock, Glenn introduced a new drummer. A German guy from the city of Karlsruhe. I understood the name as Marcus Kollmer or Kollmann. No idea who he is
What happened to Fernando?
The drummer must be Markus Kullmann from Karlsruhe. He is a huge John Bonham and Ian Paice fan. It seems that he played before with Glenn on the Spain tour in 2013. What I understand is that he played the Sweden Rock Show unrehearsed... and it sounded good!
Yes, it is indeed Markus Kullmann. He is a drum teacher and plays for various bands.
As he has posted on his websiteQuote
It is an incredible honour to announce that I am the new drummer for the GLENN HUGHES CLASSIC DEEP PURPLE WORLD TOUR 2018
