They are a thrash/melodic death metal from Cincinnati, Ohio and formed in 2000. They were originally called Estuary of Calamity. They had a lineup change and they decided to shorten the name.
These are photos from concerts where Estuary played, so they may be of other bands that played the concert as well.
