Hm honestly, it's not even about being old at all. I say the same thing about only a few years ago. Especially with the local bands I go to frequently or festival tickets. Huuuuge surge in pricing over the last few years, at least here. Maybe it's been longer in other places.
I know yyou don't like crowds. I'm sure Massive Attack would be great. But honestly, it doesn't sound like a fuck yes from you, so maybe the money's better spent in some other way?
As you said, you've seen plenty of great gigs in your life, so would missing this one be the worst thing? (and yeah, I know you said you missed others over the prices and all, but you know what I mean).
Hope whatever you decide is the right call.
Ps: had the tremendous luck of seeing Nick Cave for the first time this weekend - what an amazing night. Utterly mind blown. So happy to have got the chance.
