Surprisingly, for a side project headed up by members of From Autumn To Ashes, Biology are in fact neither a screamo nor an emo band. Instead the group, rounded out by former Engine Down drummer Cornbread Compton and producer Brian Mcternan on bass, toe the line of progressive post-rock/post-hardcore, heavy on rich instrumentation and shoegazing emotion.

Timidly paced songs with much depth and concise visions slowly unfurl as Francis Mark's rough-edged vocals are wistfully crooned. Much attention is given to instrumental build-up and sonic exploration and thus a delicate balance of vocal heavy performances and kinetic musical texturing is often struck. Quite competent overall and backed up by the addition of some strings and more, the haunting grace and pensive demeanor on display can easily compliment a rainy day.

However, while songs like "Sophisdecay" sound strikingly similar to Engine Down and "Opinions Are Like Addictions" could have been written by My Chemical Romance on a Ritalin binge, there are a lot of tracks on this effort that sadly fail to hit their stride. That's not to say they are necessarily filler, but instead that the ideas in them feel under developed and are thus left to slowly die out. That said, fans of bands like Rival Schools and Engine Down will find much to appreciate here, and with a bit more studying under their belt, Biology could easily graduate to a full-time band.
