I beg to differ, if it turns out to be The 1975, Olivia & Fender looking back from a few years in the future it could look like one of the best. I think all three have a chance to be true mega stars, well maybe not so much The 1975.
Olivia and Sam could quiet easily go on to be real house hold names and have many hits. I often look back at old festival line ups that at the time just looked good but looking back when those names having got bigger now look amazing.
I think a lot of people on efestivals are underestimating just how popular Oliva and Sam are.
