Cease Upon The Capitol were a screamo band from Nashville, Tennesse who have since broken up and formed Dolcim and Sanctions. Their sound is pretty typical of a post 2000 skramz act, as in their sound is a mixture of post-rock, punk, hardcore, screamo and thrash. They sound like a softer version of June Paik, or a darker Raein. As far as American screamo is concerned, Cease Upon The Capitol is amongst the best, in my mind. I highly recommended CUTC if you like any of the bands above, along with The Third Memory or City of Caterpillar. You can still find their records online, go buy them. Aside from their Lps and EPs, they have a demo, Splits with The Third Memory, Trikorona and Silbato, and were featured on the Emo Apocalypse and Armageddon.
Below is everything they have released, aside form the split with The Third Memory, and a video of them playing "Protocol Of The Left" in France back in '06.
