Thomas Partey, knocked back by Canadian immigration now.

I'm sure someone can update you on the clashfinder, and it will be pretty accurate by the time the festival comes around. It's a large flat-ish arena with main stage in the open air, no best side I'd say. Leadmill (3rd stage medium tent) is at the back of the main arena, T'Other (2nd stage big tent) 5 min walk round the corner. At full capacity walking around can take a bit more time though. I noticed that The Enemy are scheduled to not fully overlap with Wolf Alice, so you could catch part of their set too.   You can walk around anywhere with a beer, with most bars the usual mass market stuff, but one nice craft ale tent, back of the arena near the Leadmill stage. A main meal will set you back £10-15, but cheaper snacks also available. Expect a pint to be £7-8. Possibly a bit more this year as prices everywhere are increasing.   It's fairly easy to get to from the town centre using the tram, although can be busy at peak times / very busy at curfew. If you like a walk, it's approx 40 mins to Kelham Island (lots of indy venues) and probably an hour to the city, or catch an Uber. There will be loads of 'fringe' music events on around the city right through the weekend. Most are free. Have a wonderful trip, enjoy the festival, and your stay in our city! 

I think people on a place like this, that clearly value live music more than most, don't. I'd rather an academy than an arena every day. But I could see a few people that care about "the gram" than the actual music wanting an arena experience even if it's a mid sized band. 

The single worst shout for any slot on any stage in the history of efests. Worse even than the Wursels or The Wombles.    Unlikely I’d be there, but okay with the other two. Boy George is a class act, plus he could DJ in Block 9    

Do people want an arena experience though? Especially for sub par bands. Rather a band do more nights at an independent venue for more money than 1 big one.
