depends. been in those seats for a couple of gigs. a small part of the stage is obscured and it is quite isolated. there seems to be more scope for people who like coming in and out of their seats for drinks and toilet breaks. the sound is a bit nasty up there too. that being said I still had a great time @ ac/dc, been up in those seats for andrea bocelli and coldplay aswell and i was bored to tears, but that could have a lot do with the acts aswell though.
for leonard cohen, i'd say it's just about worth it although the ticket prices are an outlandish rip off considering there is far less cost involved with putting on these gigs compared with IMMA last year.
