Problem with SH is there’s just no vertical interest. No trees, almost nothing beyond it, and it’s approached from the flat wilderness of the Other Stage. So the ugliness of Sonic dominates the landscape, I don’t feel any joy walking towards it in the same way as a cabaret style tent.
Some of the other venues are cool. I love The Blues, and if it were inside the SE corner I/we would probably rave about it (and in it).
