I went last year, first time I’ve been since attending the first one!
It is a different festival. They really do carefully consider the lineup and the potential clashes on the days. Every aspect of the site, the bars, the merch setup is pored over and improved year on year. It’s very much a curated event, not a bundle of whoever is in the charts/magazines in the given year. See how many bands are reforming or playing special exclusive sets, it’s become the one that bands really want to play.
