The story here, more or less, is newish lead singer William DuVall, who is filling some considerable shoes: namely, those of legendary (for various reasons) voxman and wastr Layne Staley. The thing that seems to shock most people (besides the fact that DuVall's a black dude) is that the Alice Sound is more or less the same as it ever was. Those who've seen the Chains live know why this is: guitarist and lead songwriter Jerry Cantrell sings co-lead on most tracks anyway. Which is not to say DuVall's not an asset, of course, but rather to say that AIC was always Cantrell's band to begin with. As such, still worth a listen.
