I got my new headphones in the mail the other day and gave a listen to the first set of the first night.
Here are my thoughts.
Overall, a much more impressive set than I remember and really happy I was there.

free - I've always loved this song and I love how unexpected it was. Lots of awesome power.
Glide - this was new to me and I think this was close as the band got to actually speaking to the audience.
Possum - always great and while I think I've heard it at every show I've been to, it still rocks pretty hard.
Cities - I used to like this song way more than I do now. It gets good and spacey, but still kinda eh at times.
Ballad of Curtis Lowe - another new one for me....I'll probably never not skip it.
Stash - pretty reliable song that I really like, this one has trey hitting some pretty intense peak notes....a keeper
Contact - super fun and a treat....I remember the whole place being very happy during it
Sample - good version of a good song....fun but not amazing.
Kill devil falls - this song is definitely growing on me and this version is great.
Gin - a rough slow start but with tons of closing energy.

Overall a really great set with the free>glide>possum and contact being the highlights.
