I just got an email about a new blog on music cognition, Sound and Mind. From the email:
The vision for Sound and Mind is to provide an interdisciplinary hub, a place for cognitive musicologists, scientists, and critical theorists to discuss and critique each other's work and to build professional relationships, potentially leading to collaborative projects.
Go check it out.
Coincidentally, I just got a copy of Levitin's This Is Your Brain On Music, though I'm not sure when I'm going to get to it. It looks interesting, though.
