I was interested in this when it came out because they don't release a lot of albums, and I like to use the same tunings their bass uses. I had to listen to it a few times in the last couple weeks before I could say it's not bad. They throw a few licks in there from their old songs, and it sounds a lot like their old stuff without the lead vocals, which are scaled back so much you can mostly just hear Jerry Cantrell's voice.
They made a cool video:

But this one will always be the best:
