If it is an album to be known, it is this one! Many of the innovations of "Sgt Peppers" by The Beatles actually comes from this legendary album. Unexpected instruments there are emerging such as ukélé or drums to underwater sound. Various sound effects are also used: horn, bell, dog barking and train that goes at the end of the song "Caroline No". Note that one of the best tracks on the album ("God Only Knows") is the most beautiful pop song that Paul Mac Cartney-has heard. Rather disconcerting at first listen, Pet Sounds gradually reveals all its beauty and grandeur, sadly celebrating childhood dies. absolutely wonderful !!!!!!!!
