Yay Soen!
I found them last year, when my sister and I went to a prog metal festival (headlined by Dream Theater). They actually put the best performance there imho
They seem prone to copycat accusations, specifically Tool and Opeth, but I think only some songs from the debut Cognitive sounds similar to calm Tool, and after Collin's Toolvivor I felt this way even less.
So, Tellurian... I could have chose any of their albums, to be honest. But I decided on Tellurian, because it's easily their most varied album. (perhaps not a wise decision due to the nature of the game.) Even though some of it is a little proggy, it's generally not very much a hard listen. The vocals are clean and impactful, see: the outro to Tabula Rasa (the example song), and the chorus to Ennui.
I like to couple these two songs with Kuraman as the primary Soen sound, because the rest of the songs (besides beautiful ballad The Words, which is akin to "Lucidity" from Lykaia for example) are more unique to this particular album. A little mix of quiet and loud, with tasty riffs and quite perfect drum-work imo: Not stealing the show like in Mastodon, but not Seven Nation Army. It's decorated just enough to be it's own thing and not just a support to the song.
We also have Koniskas, a more mellow song with my favourite chorus on the album. Some very emotionally powerful stuff in here. And also a bombastic ending after an odd breakdown.
And the other 3 tracks are: Pluton, which is possibly the most riff focused song here. And the closing two epics Void and The Other's Fall. Void is a great contender for my favourite Soen song, the verses are so cool and I personally love the lyrics. The Other's Fall is maybe the weirdest of the bunch with a creepy middle part.
While I'm on the topic I want to say that 2 epics to close the album is great and underused. Only here and in Devin Townsend's Ocean Machine I've seen this yet.
