The Pet Sounds Sessions

The Pet Sounds Sessions is a 4 CD box set by the American rock band the Beach Boys. Released on November 4, 1997, by Capitol Records, it compiles tracks from the group's 11th studio album Pet Sounds (1966) and its 1965–66 recording sessions. The entire album is included in its original mono mix, as well as a specially created digital stereo mix. The set also contains instrumental tracks, vocals only tracks, alternate mixes, and edited highlights from the recording sessions for many of the album's songs, along with several tracks not included on the album. The box set was nominated for Best Historical Album at the Grammy Awards of 1999. In 2011, it was followed by The Smile Sessions, a similar compilation devoted to the recording of the Beach Boys' unfinished Smile project.

Pet Sounds was first released in 1966 in monaural and duophonic formats. The new mixes created for the box set were made in January–February 1996. Linett wrote: "In mixing Pet Sounds in stereo, every attempt was made to duplicate the feel and sound of the original mono mixes. Vocal and instrumental parts that Brian left off the record in 1966 were noted and duplicated, as were the fades." 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."

AllMusic calls the compilation "a fascinating, educational listen, even if it's not necessarily indispensable." 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."
