I know the book has been out for a while, but I just found out that there is also an audiobook version of this. What I think is particularly interesting about this, is that Phil actually narrates the book, and also there is a "soundtrack" in this with many Dead song excerpts. It brings the whole thing more to life.

I bought it here: http://www.AnEarForBooks.com/Title.aspx?titleId=1786

I know some other web sites are selling it also.

Hope some of you check it out as it's very cool!
