Query: Greatest Elvis Album Ever

I've listened to almost every Elvis Album released, and without a doubt this edition of Aloha From Hawaii, is by far the greatest show he ever put on. The sound is crisp, and his voice has never sounded more alive. His performance was outstanding, if you ever thought about purchasing an Elvis album, buy this one today, you won't be disappointed. If you weren't a huge Elvis fan already, after you hear this, you will be.
