Bioluminescence by Dawn of Ouroboros is a bit of a hit and miss, but in a strange way. Chelsea's vocals are great, and the stark contrast between her cleans and growls fits directly into the instrumentality of the album (and band) - dark, dissonant heavy sections with almost whimsical softer passages. The guitars, while clearly working on overtime pay, are a little difficult to parse and discern (at least the subtle melodic lines during the heavier sections are) within the entirely of the mix, which takes away from the overall impact the individual instruments could have made. Regardless, Bioluminescence, like an ode to it's name, is exactly that: motes of light among the dark and dreary, which captures the essence of an aggressive, blackened, yet ethereal and majestic sounding album.
