Advice for Upcoming Tour

Hi everyone, I would consider myself a pretty well rounded Dream Theater fan but I’m gonna be brutally honest I still haven’t listened to a change of seasons.

I’m seeing them again this fall for their Parasomnia/ACOS tour and I was wondering if you guys think it would be more fun for me to listen to ACOS before the show, or experience for the first time in concert. I only ask because I heard a few tracks for the first time at a show this past year (Dark Eternal Night, Barstool Warrior, The Mirror) and they are now some of my favorite DT tracks. My only fear with doing this is that it will be too much to take in, and that’s because it took me a few listens to really appreciate Octavarium (my now all time favorite track)

TLDR: Should I listen to ACOS before the show or hear it for the first time in concert?
