I forgot the empire- judging from the simple minds concert there a few months ago, then that would be better than the phil. I like to have a seat these days- can't be arsed with dancing, jumping, pushing, getting cig burns on my clothes (although that's stopped now, thank god) people spilling ale on me, etc.
Concerts abroad are miles better. I've been to a few in Mexico and you just sit down and they bring the beer, pizza, hot dogs, etc., right to your seat. The only time you have to get up is to go the toilet, which is quite often as you always end up drinking loads (well..it's hot...).
