That's been out of print for at least 6 months.
You MIGHT be able to get it direct from Mississippi records, but I doubt it.
Mississippi also did "Last Kind Words" comp which is amazing as well and some current artists which I haven't heard.
There is a Yazoo (Shanachie?) CD of Washington Phillips, which is where Mississippi
probably got the stuff from.
That Phillips LP does look really cool, though, it has a fake "Folkways" styled sleeve.
Didn't I review it here?
