Curious to see what the balance will be with this one

either never or almost never... the best concerts for me always carry an element of surprise.

I'm assuming you're not counting being handed a program at the door, so I have to say never.

Yes, because I use it to determine whether or not I want to attend to the concert.

If it's a band I don't know the entire discography is I will, so I can catch up on the relevant material. If it's one of my all-time favourites that I know inside and out, I'll leave it to surprise.

Almost always regardless of the band.

No, but I haven't had the chance to see a band who had a mixed batch of work (by my preferences/standards, obvs). If The National swung through I may very well see if their recent sets were heavy on High Violet, and seeing that they were, I may skip.

Usually not, but I will for some major artists. Usually I follow what McCartney and Ringo are playing when they're on tour whether I'm going or not. Maybe for Dylan since he's always changing it up so much.

I have not done this once

I tried this once cuz someone sent me one and it actually made the concert seem longer and drag

Never. I like the surprise. Seems like nearly every concert I go to, the artist ends up playing a really off-the-wall setlist anyway, so I wouldn't want to spoil that.

If they have a recent album that I don't care for, I may check before buying tickets, although this is usually unnecessary. I don't need to do any research to know I shouldn't bother with Magnetic Fields shows for a while.

Never. I like going in and being surprised (and trying to guess what they will play).

Considering in the last 3 years, the only shows I have seen are by Phish, and in 1500+ shows, they have never played the same setlist twice, I always check the setlists leading up to the show. That way, I get a sense of how they have been playing recently, and I never have to risk knowing the setlist ahead of time. It will always be a surprise.

sometimes, but you probably shouldnt
