For Drakeophiles, the ground-shaking news here is the unearthed ''Tow the Line,'' a threatening-clouds folk-blues that's of a piece with this cult icon's other final recordings. The iffy news is that about half of the still-available ''Time of No Reply'' rarities set are also here. The additions -- like two songs with newly dubbed-on strings -- are a tad suspect. But the ageless, mythopoetic elegance of Drake's craft shines through, even if we truly have heard some of this before.
