With a name like Innsmouth and the title of the album here, you can probably guess that there are a lot of Lovecraftian references to be found herein. You would be absolutely correct. Song titles like "Thrice-Blessed Shub-Niggurath" and many of the lyrics also keep that going.
But along with the obvious lyrics and band name, the sound really conveys the hopelessness and foreboding doom of the Lovecraft stories. The sound is otherworldly, dark and intense, with rumbling riffs and psychotic growling vocals. There is a creepy atmosphere that carries throughout the entire album, which is conveyed the best through the use of audio effects such as those at the beginning of "Thrice-Blessed Sub-Niggurath".
The riffs in this release are not particularly ground-breaking. They are not overly progressive or strange. But they work incredibly well, particularly with the vocals. The riffs are fairly repetitive, but that is definitely not a bad thing when they sound this good.
This album is definitely a contender for Album of the Year for me. It is one of those death metal albums that just grab you and refuse to let go. Definitely a must-hear.
