I'd love them to be on the Revolut stage, I just wonder if the smaller stage can hold their equipment. I remember they destroyed a biggish stage at Primavera Porto this year.

Not much of a draw if you only like English-language music, but a lot of the Spanish artists who play FIB are great. When I went last year, I had a lot more fun watching great live performers like Xoel Lopez or Siloe (who are back this year) over English also-rans like Miles Kane. And of course the location is beautiful!
