With the second half of the epic "House of Gold and Bones", Stone Sour have crafted a masterpiece. This half is much more experimental and progressive than the first, ranging from gloomy, piano led dirges (Red City) to hard rock anthems (Black John, HOGAB, Do Me A Favor). All in all, a truly fantastic album which will secure Stone Sour's place among the greatest bands of our generation.
Also, in order to maximise your listening experience, listen to both albums back to back. Incredible.
