Wilson's growing mastery of the
recording studio and his increasingly sophisticated songs and complex arrangements would reach a creative peak with the acclaimed LP
Pet Sounds (1966). The tracks "
Wouldn't It Be Nice" and "
God Only Knows", showcased Wilson's growing mastery as a composer,
arranger and producer. "God Only Knows" is said to have been the first pop single ever released in the U.S. to include the word "God" in its title; supposedly for this reason, it was denied radio airplay on many stations and only reached #39 on the national singles chart. "Caroline, No," also taken from
Pet Sounds, was issued as a Brian Wilson solo single, the only time Brian was credited as a solo artist during the early Capitol years.
The album's meticulously layered harmonies and inventive instrumentation (performed by the cream of
Los Angeles session musicians known as
The Wrecking Crew) set a new standard for popular music. It remains one of the more evocative releases of the decade, with a distinctive strain of melancholy and nostalgia for youth. The album is still widely regarded as a classic of the rock era. Among other accolades,
Paul McCartney has named it one of his favorite albums of all time (with "God Only Knows" as his favorite song). McCartney has frequently said that it was a major influence on the Beatles' album,
Sgt. Pepper's Lonely Hearts Club Band, similar to Brian Wilson stating he was inspired to make
Pet Sounds upon listening to The Beatles'
Rubber Soul. Despite the critical praise it received, the album was indifferently promoted by
Capitol Records and failed to become the major hit Brian had hoped it would be (only reaching #10). Its failure to gain wider recognition hurt him deeply.
Because of his withdrawal from touring, Wilson was able to complete almost all the backing tracks for the album while the Beach Boys were on tour in
Japan. They returned to find a substantially complete album, requiring only their vocals to finish it off. There was some resistance from within the band to this new direction. Lead singer Mike Love is reported to have been strongly opposed to it, calling it "Brian's ego music," and warning the composer not to "fuck with the formula." Other group members also fretted that the band would lose its core audience if they changed their successful musical blueprint. At Love's insistence, Brian changed the title of one song from "Hang On to Your Ego" to "I Know There's an Answer." Another likely factor in Love's antipathy to
Pet Sounds was that Wilson worked extensively on it with outside lyricist
Tony Asher rather than with Love, even though Love had co-written the lyrics for many of their earlier songs and was the lead vocalist on most of their early hits.
Seeking to expand on the advances made on
Pet Sounds, Wilson began an even more ambitious project, originally dubbed
Dumb Angel. Its first fruit was "
Good Vibrations," which Brian described as "a pocket symphony". The song became the Beach Boys' biggest hit to date and a US and UK # 1 single in 1966 — many critics consider it to be one of the best rock singles of all time. In 1997, it was named the "Greatest Single of All Time" by Mojo music magazine. In 2000,
VH1 placed it at number 8 on their "100 Greatest Rock Songs" list, and in late 2004,
Rolling Stone magazine placed it at number 6 on their "500 Best Songs of All Time" list. It was also one of the more complex pop productions ever undertaken, and was reputed to have been the most expensive American single ever recorded at that time. Costing a reported $16,000, more than most pop
albums, sessions for the song stretched over several months in at least three major studios.
In contrast to his work on
Pet Sounds, Wilson adopted a modular approach to "Good Vibrations" — he broke the song into sections and taped multiple versions of each at different studios to take advantage of the different sound and ambience of each facility. He then assembled his favorite sections into a master backing track and added vocals. The song's innovative instrumentation included drums, organ, piano,
tack piano, two basses, guitars,
electro-theremin, harmonica, and
cello. The group members recall the "Good Vibrations" vocal sessions as among the most demanding of their career.
Even as his personal life deteriorated, Wilson's musical output remained remarkable. The exact nature of his mental problems was a topic of much speculation. He abused drugs heavily, gained an enormous amount of weight, suffered long bouts of
depression, and became
paranoid. Several biographies have suggested that his father may have had
bipolar disorder and after years of suffering, Wilson's own condition was eventually diagnosed as
schizophrenia.
