I'll hold back extensive comments until I hear the whole Black Ice album. Going by the reviews on Amazon, it's fine. The only bad reviews are suspected lugheads who think they are now too good to like the band. There's nothing wrong with being a kid again for an hour or so, and nobody should be surprised that AC/DC sounds like AC/DC. I don't think one reviewer realized how idiotic he sounded to criticize the band for retaining their same sound.
If he wants a new sound, go find a new band. The trailer parks, the last bastions of American freedom, will be rumbling this winter.
