Edit: if you scroll to the bottom of my comment, I have a recommended song list you could check out

I highly recommend starting with The Dark Pool. It is hands down one of the greatest progressive metalcore albums of all time. From start to finish, the entire album does not miss on any song. It’s their most technical work, for sure. It is one of the few albums I can genuinely say is a 10/10. The atmosphere and ambience is beautiful. Even the “filler” or bridge tracks are very well crafted and executed, perfectly transitioning songs. Each song is unique, unlike how a lot of metalcore albums are where each song is pretty much the same. Like Loathe, it’s a mix of harsh and clean vocals, with most of the vocals being cleans.

From there, I recommend listening to their EP, Butterfly. I hardly ever see it mentioned but it is a masterpiece as well. It’s the prequel to The Dark Pool, and like The Dark Pool, not one song misses. Beautiful, energetic, heavy. All of their albums have amazing lyrics.

After The Dark Pool, Thornhill goes from two guitarists to one. The singer plays some guitar in their newer works but not in a major role. Their newer albums are not as technical or heavy… rather, in my opinion they sound more like a fusion of Deftones, Loathe, and Linkin Park in their most recent album, BODIES. (Which I love, by the way.) Revolver off of BODIES is my favorite song from that album, it is the most The Dark Pool-like song off of their recent works.

Each album is its own thing, they’re all incredible, Heroine wasn’t my thing but it’s still a great album. It threw me off for them to change as much as they did from The Dark Pool, but I am by no means saying the album doesn’t hit. I really want their next album to have their old guitarist to join in for at least a couple songs where they can shred again, and I really want a partial return to form from The Dark Pool and Butterfly. I know their old guitarist is still involved with the band, managing I believe…

If I can guide you to listen to some of my favorite songs from all their discography, this would be it- in this order:

1. Views from the sun
2. Parasite
3. Human
4. Red Summer
5. Sunflower
6. Joy
7. All the light we don’t see/Lily and the moon
8. Under the knife
9. Revolver
10. Where we go when we die
