The first word I could think of for this album is "Radiohead". Maybe my head remembered some review comparing it to PJ's contemporary. And as I was writing that I just got to "This Mess We're In" and Thom is featured. Makes sense now.
In addition to that, the guitar work feels very late 90s/early 2000s alt-rock. Compared to "Dry", the last album I listened from PJ, it feels more introspective and "transient". Not sure how to put it into the words but the album cover evokes that evening/midnight feeling of walking around NYC and seeing people and lights coalesce into one.
As always, I'm more of a sucker for the more simple tunes like "This Is Love" and "This Mess We're In". The second half stood out to me as sounding more different than the first half, which to me were just variations of the same rock sound (3-3.5).
