If you know the Books and Prefuse, then you know exactly what this collaboration will sound like. Its fantastic, don't get me wrong, but just as it starts to get going, its over. I've listened to it several times, suspecting that I would soon tire of it, but I haven't. Much like the Books' albums, they only grow over time as you engage in more in depth listening. Its actually interesting that clips from their last three albums make apppearances during the EP. However, a part of me was really expecting to be surprised by what I heard. Each of the Books' albums has been a surprise as they change and grow into their sound. So, something in me was hoping for that moment of "wow, I didn't see that coming." It never came, but the strength of this EP further lends credence to the importance of these two artists. It compliments their full-lengths, and is a must for fan of either artist. I used to be a huge fan of Prefuse (pre-surrounded by silence), and was glad to find him try his hand at something of this magnitude. Overall, a great listen, just not long enough, or adventurous enough......
