was used to transfer the analog reels to digital multi-tracks – the same model used for Pet Sounds. The mix was then processed through an original tube console from United Western Recorders in the 1960s. Some exceptions remain, and so the stereo mix of Pet Sounds does contain some differences from the original mono mix. Among them, alternate vocal parts used for the bridge of "Wouldn't It Be Nice" and the end of "God Only Knows" due to the original tracks no longer existing. "You Still Believe in Me" features a single tracked vocal instead of the doubled vocal of the original due to a missing tape. In the mono version, chatter can be heard buried in various tracks; instances of them were omitted from the stereo version at Brian's request. Release There was a minor controversy regarding a significant 18-month delay in the release of the box set (originally planned for May 1996 to coincide with the 30th anniversary of the album's original issue). Reportedly, Mike Love was dissatisfied with the accompanying essays that allegedly understated his involvement in the album's making. The original liner notes had featured none of his comments, even though other band members were interviewed, and new notes were subsequently commissioned to Dennis Diken. Biographer Timothy White said that "The Beach Boys apparently didn't get the track selections until late in the production phase, and they all had misgivings about how Capitol envisioned it." Reception AllMusic calls the compilation "a fascinating, educational listen, even if it's not necessarily indispensable." Q gave the "enlightening" box set a perfect score and wrote that "the backing music tracks sans vocals opens your ears to a bevy of awe-inspiring nuances previously obscured by singing. At the same time, the isolated vocal tracks are nothing less than spiritual in their emotive wallop." The New York Observers D. Strauss called the stereo mix "pointless", adding, "I must admit that, as a music geek, listening to Mr. Wilson hold myriad consultations on when to beep the bicycle horn in 'You Still Believe in Me' carries a portentous thrill". The compilation was pivotal to the inception of the Brian Wilson biopic Love & Mercy, as director Bill Pohlad enthuses: "It's just so beautiful and impactful for me to listen to that. So the idea of trying to capture that on film was certainly a big part of my interest in making the movie."
