Alright, so I will comment a little about them
First of all, I dont see much of sludge or drone in their sound, althought that doesnt really matter.. To me they are a product of the noisecore scene, just like Neurosis, although they went into a direction that is completely their own. They totally avoid any of the wankery that Pelican displays and as a result are really able to make a phenomenally oppressive, yet beautiful wall of sound. They also occasionally have vocals, which remind me a little of Alice In Chains (actually, they remind me of the vocals in the French industrial band Sin, which reminds me of AIC, I just made a shortcut, LOL). This is music for fans of ambience, noise, textures etc...
Funny bit of trivia - they are now called Continuum Research Project (or 5ive's Continuum Research Project, according to some sources) due to the fact that there is already a boys band called 5ive
This must have been a little embarrasing for them when they found it out, LOL
