GRRM has posted on his "Not a Blog" that an audiobook will be produced of Dreamsongs (Volume 1, Volume 2), the massive and exceptional collection of a large part of the body of George’s short fiction from his earliest days to the present. A number of different readers will be involved, and most fascinating of all is that George himself will be reading the interstitial introductions to each section of the book. These are some of the best parts of an already-great collection, thanks to the autobiographical insight into George’s life and work.
Note that the "Not a Blog" entry also includes word on A Dance with Dragons, including semi-spoilerish information.
