With Impressions Prion show a more technical and brutal approach. The music is now death metal in the vein of Hate Eternal with many references to Morbid Angel. The music don't differ a whole lot from the aforementioned bands, but Prion has enough substance in the music to make it work. From the first notes it's apparent that the Argentines know what they are doing. The trio proves they know how to play fast, versatile and tight death metal. It certainly doesn't hurt either that a solo or two regularly appear.

The music is mostly very fast, but it's not grind and blast in total abundance. Prion is able to uphold a healthy balance between the fast and the more mid-tempo like parts. The variation is also what makes Impressions an enjoyable listen. The production is close to those of Hate Eternal and Morbid Angel. Again it doesn't exactly make the difference any bigger, but it fits the style and music. The sound is clear, but a little dry. Nothing seems to vanish in the soundscape. Impressions is nuanced and well-balanced effort that should appeal to fans of abovementioned bands and fast, technical death metal in general.
