The article meets the |general notability guideline, as it "has received significant coverage in reliable sources that are independent of the subject."  , in talking about "unreleased material", doesn't seem to distinguish between albums that are planned for future release and those, like this one, that are not.  But it says, "Unreleased material (including demos, mixtapes, bootlegs, promo-only recordings) is only notable if it has significant independent coverage in reliable sources."  That is the case here
