The problem with double albums is that it is hard to stay consistent for so long, and to deliver quality over the equivalent of 2 records. The results on this one is, as you might expect, unequal. Some really good pieces, mixing different genres (including jazz, good electronica, and so on), and more repetitive/boring pieces. I'd happily cut it in half, keep the best half as the "real" album, and the second half as the additional record you sometimes get on deluxe edition and, let's be honest, you never listen to because it's not that good.
