Hurrah! From the local rock station The Fox I learned of new music from AC/DC and Metallica. This follows the release of Rush’s “Snakes and Arrows” last year; I regard those three bands as the greatest of hard rock. So far I’ve spent only a few minutes listening, but I’m excited so far. Metallica’s “The Day That Never Comes” indicates the band has gotten comfortable again with subtle composition; the group’s best songs are very well written. And piano on “Unforgiven III?” Take that, genre zealots. It’s a good song. And nothing else matters.
