There is honestly a LOT of bands I am really looking forward to. My top 10 are probably Orphaned Land, 1349, Bury Tomorrow, Marduk, Elvenking, Iron Maiden, Kampfar, Therapy?, Tsjuder and Myrkur.
When was your first Wacken? Mine was 2015, so 2016 will be my second. I was a regular at Bloodstock from 2011-2014 though.
