Review Summary: Verdict? Buy it, now.
This album was first contact to Project Silence's work for me and I'm damn glad since I loved it! After listening this one I eventually did listen their older stuff, but I wasn't so impressed with those than with this one. Their older stuff is really good, but nothing like this.
Slave To The Machine being their second full length album, it is clear that band is going towards specific style and moving to black metal sound and heavier industrial (After hearing those as well), as their earlier works were more techno/electronic oriented.
Songs are fast (mostly), but it has a slow black metal atmosphere that paints great and massive atmosphere, it tends to innovate a bit and one can feel that the band was not afraid to go into a more groovy sound (The Era Of Fear, Sick (Slave To The Machine), Perversion are good examples), therefore allowing heavy headbanging on almost every song.
Fifteen songs, 55 minutes of non-stop headbanging (except one electronic song in the middle, but still fast) every songs has the same vibe/atmosphere but yet they're totally different and recognizable from each other. Lyrics are great, guitarist's work is a must, same goes for the drums and bass. Vocals are mixed with electronics and distortion, but screaming and growls are great with a lot of emotion. You can have top-notch heavy screams, but if I can't feel the emotion behind the heaviness (anger, pain, hatred). there is not much to say about vocals. In this case vocalist obviously manages to carry that raw feeling of anger, which is really good.
So, that's that. Verdict? Buy it, now.
