When I went last, over a decade ago, it had hot tubs (pretty grim tbh and sponsored by some corporate giant), more sponsorship than you could imagine (it's festival republic's big money spinner after all), plenty of spoken word poetry stuff, and it has hosted (thanks to a quick google) George Ezra in the past. Yes, it's full of young people and therefore feels a bit edgier but it's not really. It's also really fine that the audience is middle class, as long as it is welcoming and fun, honestly, who cares? Excluding people by labelling events only available to one class is pretty stupid tbh.
And if you do really care about making music more accessible, then without derailing the thread, we need to subsidise and support the arts sector in a way that allows more people to get involved in it and not leave venues to die, and artists to have to make serious choices about whether continuing in music is the correct career choice.
