The music of Ahasver is a hybrid style that takes elements of a few different styles, including technical, groove, extreme, sludge, and post-metal, into its progressive makeup. The band’s layered approach to songwriting is enjoyable and engaging. Despite being their debut album, Ahasver appear to have found their voice already, and what a multifaceted and rich one it is too.
The songs are heavy, yet textured. They have multiple moving parts, meaning that they sometimes show a complexity that can be almost hidden; the band make this look easy, but under the hood there is sometimes a lot going on.
For a simplistic overview of Ahasver’s sound, first think of a many-sided sludge metal approach to extremity, sort of like a cross between Neurosis, Mastodon, Dvne, and Isis. Then, throw in the occasional bout of technicality and/or extremity that wouldn’t be out of place on an album by The Dillinger Escape Plan or Gojira, and a rhythmic quality that recalls a mix of Converge, Godflesh, The Ocean, and Keelhaul. The music also boasts a sense of songwriting catchiness that’s unusual for such a band that leans towards the more extreme side of the heavy music spectrum; Ahasver know how to write a good tune it seems. Add to this bucketfuls of mood and atmosphere, and you have an atypical mix of styles and sounds that all add up to a very compelling collection of tracks.
My only criticism is the extended sample/feedback section at the end of the final song, which is just unnecessary.
Ranging from brutal crushing heaviness to soaring beauty, Causa Sui has a lot to offer fans of heavy music. Ahasver have impressed with their remarkable debut album.
Very highly recommended.
