Query: Forget "Nevermind"

All I will say is that "Say Hello 2 Heaven" Is the single greatest vocal perfomance in the history of rock. When you hear Chris Cornell blast out with shaddering emotion on this track, you will be blown away, just like I was. Eddie Vedder, another great singer, also appears throughout the album, adding beutiful harmony. "Say Hello 2 Heaven" is indeed the single best vocal performance in the history of rock, and is reason alone to purchase this CD. Overall, most of the songs are good, and the album is one of the most underrated of all time.
