Pinkpop:
Acts I will definitely see: Foo Fighters, Pearl Jam, Bruno Mars, Nothing But Thieves, A Perfect Circle, Greta Van Fleet, Triggerfinger, The Offspring.
I have never seen any of these acts and some are quite new but promising (Nothing But Thieves and Greta Van Fleet).
What I like about Pinkpop is that the festival isn't really tied to any genre. Last year I saw artists such as Clean Bandit and Imagine Dragons, whom I wouldn't buy tickets for in a million years, and I really enjoyed seeing them. Some pop artists are a real bore on the radio but aces live. This is why I like going to more pop-orientated festivals; all the acts in the genres that I love I will more likely go to on their own respective tours.
So I'm organizing a mini-festival "Sonorous Fest" (6-7 bands) on the 23rd of June in Baroeg @ Rotterdam with 3 other mates. Genre mostly revolves around metalcore/hardcore and we'll be revealing more info soon through these platforms, probably not the type of music the dutch fellows over here are interested in but just thought I'd let you know.
Not my jam unfortunately, but I hope it will be a succes!
