The superlatives heaped on Unknown Pleasures, which regularly makes the best albums of all time lists that magazines insist upon publishing, are well known: sonically groundbreaking, birth of postpunk, early Goth template, integration of electronica, etc. It is hard to imagine anyone remotely interested not having a copy already (or two, or three, between vinyl and previous CD issues). So the question is -- does the remastering justify purchase, despite the fact that all but two tracks on these two discs are on the Heart and Soul boxed set? The answer is yes -- far more space on the individual instrument tracks on the studio album than on the box set, and the mastering is louder, as most CDs are now by comparison to 10 years ago. The live album is still a bit ropey, but interesting, and the remastering definitely justifies repurchase.
