Vocals?! Wow, strange little release, but nice. Very nice. Endif's contribution is like a perfect cross between rhythmic noise and pure electro in my opinion. Not rhythmic noise with a dash of electro and not electro with a dash of rhythmic noise, but a perfect blend. There's even a hint of hard house on the Caustic remix of "Sleeper Cell". I was actually very skeptical of this release; I almost didnt buy it not knowing either of the artists thinking they'd be closer to electro-industrial rather than pure electro and rhythmic noise. As for Caustic's side of things, the tracks are a lot faster and the house influences are a lot more prevalent and with a repeating sample saying "Tell me about my uterus", you just have to love it. Caustic, unlike Endif doesnt make use of vocals, instead relying on various voice samples throughout. Highly recommended!
