I went. They came on stage at 2:40 am. There was a big curtain across the back of the audience and supposedly they weren't letting people in late. Dunno if they enforced this. The stage was pitch black. I couldn't even see Sean and Rob enter or exit the stage. The sound was amazing, massive bass, very clear and loud. The drums were incredibly punchy. The set was exactly an hour and quite similar to the 2022 stuff, the ending was slower and quite funky.
Otherwise at the festival, a lady I was talking to said she saw Elon Musk at the side of the stage when Grimes was playing flaunting the "no photography" rule. And I saw a shooting star as I was walking back to my hotel.
