I could write an opus, wax clever, contrast compare and cogitate ad infinitum, but it looks like I've been well beaten to it. And there are a lot of "I want my new Chris Cornell album to sound like the last one/everything he's ever done before" brigade.
Fine, if that's what you want, don't waste your money.
If, however, you fancy the thought of the best vocalist in the business trying something new then open your ears and your mind and get ready to have your perceptions shifted.
I thought some of his last album was awkward and clunky ('No Such Thing' and 'My Poison Eye' are good examples, although I eventually grew used to them) and when I heard Timbaland was involved and guitars mostly weren't, I have to admit I shuddered. But ever since I got it, it's hardly been off and even when I'm not listening to it, I can hear chunks playing in my head.
It comes down to this. Listen to it. Make your own mind up. If you don't like it, that's no problem, it's not like Cornell's rock canon is sparse. But if you do like it, I guarantee you'll be glad you gave it a chance.
