I wish more box sets would come out that fully explore an album. This is the third time I've bought Pet Sounds. I upgraded to the stereo version thinking that the box set would be overload. I'm so glad I upgraded again. This is almost a religious experience. The vocals only section of the box set is worth the money. Not to mention the original speed version of Caroline No, which was sped up for the original release of the album. The slower version is hypnotic and I think portrays the emotion of the song as originally intended. This box set is totally worth the money.
