Regarding "Privateering", is true that mixing the songs makes it more wide in musical terms, but artistically, put the blues songs apart in a blues record it would had been nice too.
I think that the only reason we are having a cd and an ep for the new recording songs is that MK thought the new songs were good enough but he already had the cd mastered and didn't want to redo it again, so kept the cd mastered and decided to release those extra songs apart.
Let's see if he release both things at the same time or maybe as LE suggested, the EP waits to the Record Store Day, which I hope he doesn't, as that is November, I think...
