believe it or not, i actually didn't wear earplugs during both roseland shows...and i didn't experience any worse ear-ringing than i do when i play drums with a full band. i didn't want to experience MBV with anything blocking the pure sound, so i decided to watch from the middle, towards the back. i didn't feel it was necessary to be so close (and it's much easier to get a beer when you don't have to wade through a crowd). it was loud as fuck, to be sure, and if it were any louder i would have needed earplugs, but i think i was in the perfect position to listen. so...if you want to be close, definitely wear earplugs, but if you stand towards the back, you could probably get away with not wearing them.
i wish this show was on 7/31 because i would see them again. i have polvo and obits at johnny brenda's on 7/30, and seeing polvo again is just as high a priority for me as MBV...and much more financially feasible!
