What concert would you go back and see if possible?

I don’t know if this has been posted yet but I was talking with one my best friends about it so im curious if yall could go back and get pit tickets to one show from the past what would it be? For me it’d be slipknot in london 2002 when they did the Iowa world tour. It’s my favorite album of all time and it’s in my opinion one their greatest shows of all time.

if i had to be specific it would probably be p!atd denver 2006. but i would’ve loved to been able to see nine inch nails or nirvana in the 90s. tempted to say NIN’s 1994 woodstock performance but idk if i could handle all that mud,,,

There are a lot of concerts I really wish I could've seen but the king is easily Boards of Canada at All Tomorrow's Parties 2001. Last time they ever played live and most of the bootlegs out there are in terrible quality (with the exception of the soundboard that leaked earlier this year).

Otherwise it'd probably be Ween at John & Peter's on December 30th, 2000. They played almost 50 songs over the course of about four hours that night. I have a bootleg of it and it RIPS.
