Query: Greatest underrated album

I can honestly say that this album made me a real fan of Pearl Jam. I had bought all of their previous albums and enjoyed them all but this one was different. Up until this record came out Pearl Jam could do no wrong. All of their songs were in constant radio rotation and to many people this record just didn't rock like the older ones. I think this record sounds better because a lot of the angst of grunge rock was gone from this album. I encourage everyone to pick this record up and give it a listen. I think you'll be suprised.
