Sorry if this has already been mentioned: "Mountains On The Moon" it is.
Five songs from this 3CD set can now be heard "officially" via the
YouTubes. As much as I like Jenny Lewis, Courtney Barnett's take on "New Speedway Boogie" is the absolute highlight. In fact, I bet it's better than all the other 58 tracks. And better than the whole Grateful Dead discography.
