Wow. So beyond surprised at how good this is. I was hoping it would be good and my expectations are succeeded.
Christopher hit the nail on the head. I absolutely love the outro as well. They brought back the rain and bells from the song Black Sabbath. Now it kind of feels like everything has come full circle 43 years after the S/T album came out. This will be an easy lock for the end of 2013 list on here.
Also this talk of Volume 4 has me wanting to revisit the album again, I don't care for the album a lot but I feel like I need to try it again.
