With our album reviews, we try to keep our posts about fairly new material. We may be a few weeks or even a couple months behind...but you're not going to be reading a review of "Master of Puppets" like it's some new album.
In this section, we're going to be a bit more flexible. This is a music site, so the only books here will be music related, but they're not necessarily going to be the newest releases. One of the main reasons is that you really don't see many relatively in depth music book reviews. I frequent a few different metal/punk/hardcore sites and none of them offer book reviews.
