Here's a puzzle: What kind of music is this jazz trio (piano, bass, drums) actually playing? Post-rock? Acoustic IDM? Given the through-composed nature of the nine linked songs, we're calling this "modern classical." (The additive parts of tracks like "Atlas" hark back to early minimalism.) Much of this album grooves with a straightforward energy, though "Ijiraq" has surprise jabs galore. "Nix" is the closest thing to a club-ready beat, but also takes an interesting turn. "Moon" is spacey, while "Ymir" and "Algol" both bring up the BPM -- and set up the title track as the satisfying come-down.
