This album grooves like a motherfucker!!! If you like nasty JUNS and DJENTS on guitars, and polymetric (Meshuggah style) grooves, you must hear this. There's a little bit of filler on here, but tracks 1, 3, 9,10, and 11 are incredible, and have breakdowns that rock so hard, your head will cave in and implode. Drums are grimy sounding, but tastefully restrained with small subtle (but colorful) fills. The bass has a nice tone, and holds a tight groove with the drums, more noticeably when the guitars pull back to play clean interludes. The vocals are very harsh and may turn a few people off, but they grow on you. The similar sounding high pitch shrieks from the two vocalists are nothing special, but the harmonized choruses work quite well. This album is far from perfect, but is still a fun album to listen to, and up amongst the highest play counts in my iTunes library. There is a definite Meshuggah influence, but unlike other Djent bands, Fellsilent just keep it simple, and raw as hell. Clever riff phrasing is used but in a way that makes it seem complex, but simple enough to bang your head to. To put it simply... You know the outro riff on New Millenium Cyanide Christ?? ... Well, this whole album is full of badass riffs like that.
