Have been following the topic for a while but decided to join the discussion.
I absolutely do not understand the hate for the double mainstage concept on this forum. It works amazingly on Graspop and Hellfest for example.
I see a lot of people on here asking for new headliners, younger headliners etc. double mainstage is the way to do this. You would get to see a lot of amazing headliner shows from bands that you normally would not. It does not matter that it is not 2 huge headliners, the chance to see younger bands given the opportunity to show their headline show even though they aren’t headliner status yet give full blown headliner shows is amazing. I see people criticizing bookings like Iron Maiden, Def Leppard, Ozzy, Kiss etc but just imagine that after these ancient bands are done with their set you get to finish the day with a younger more exciting band like Parkway Drive, Lamb of God, Deftones, BMTH, In flames, Amon Amarth, Korn etc etc.
People are complaining that BMTH were not given the chance to headline a long time ago, the reason that this has not happened is that there is only one mainstage. Imagine having Iron maiden from 21:00-23:00 and then after that having a full blown headliner set by BMTH after that to finish the night.
I don’t see the issue with having more insane headline worthy sets in the dark without losing anything.
As someone that visited Graspop a lot, the headline shows that I remember from Graspop were not the fossils of Scorpions or Def Leppard or whatever, but the headline sets of Parkway Drive, Lamb of god or Korn that followed after. The fact that they were not the biggest band on the bill does not matter.
