Unfinished album Dennis continued writing songs for the Beach Boys' subsequent albums, including
Sunflower (August 1970), which featured the single "
Forever" – commonly regarded as one of his finest songs – and three others: "
Slip On Through", "
Got to Know the Woman", and "
It's About Time". Their inclusion was said to be at the insistence of
Warner-
Reprise, who felt that Dennis's songs sounded more contemporary than other rejected Beach Boys tracks. On December 4, Stateside/
EMI released "
Sound of Free", a single issued only in Europe and the UK under the credit "Dennis Wilson & Rumbo". The B-side was the
Sunflower outtake "
Lady" (also known as "Fallin' In Love"). At the Beach Boys' concerts in 1971, Dennis played solo piano renditions of his songs "Barbara" and "I've Got a Friend". Biographer
Jon Stebbins writes, "He was developing a
power-ballad style that would become his signature." Dennis's two song contributions to the Beach Boys' August 1971 album ''
Surf's Up'' – "
4th of July" and "
(Wouldn't It Be Nice to) Live Again" – were left off the record. At the time, Dennis stated that he "pulled" the songs off the record because he did not feel they flowed well alongside the other tracks. According to band manager
Jack Rieley, the absence of any Dennis songs on ''Surf's Up'' was for two reasons: to quell political infighting within the group concerning the album's share of Wilson-brother songs, and because Dennis wanted to save his songs for a solo album. Engineer
Stephen Desper said of Dennis's album, "ninety percent of it was ninety percent done". Fred Vail, the band's co-manager, described the album as "diamonds never cut and polished", and explained, "The Beach Boys obviously weren't buying into his songs as part of the group output." Several tracks from the album – "Baby Baby", "It's a New Day", "I've Got a Friend", "Behold the Night", "Hawaiian Dream", "Medley: All Of My Love / Ecology", and "Before" – were released on the 2021 box set
Feel Flows. In June 1971, Dennis injured his hand badly enough to prevent him from playing drums for some time, so
Ricky Fataar took over as the group's drummer between 1972 and 1974. Stebbins writes, "Now, during concerts, the impulsive, physically aggressive Dennis would be reduced to sitting behind a keyboard or standing off to one side behind a microphone. It hurt him deeply. He felt like a caged animal. His drinking became worse and his participation in the band became erratic." Biographer
David Leaf wrote that, by this time, "Dennis was constantly quitting [the band] or getting fired and then rejoining." Two more songs intended for Dennis's album – "Make it Good" and "Old Movie" (retitled "
Cuddle Up") – were ultimately placed on the Beach Boys' 1972 release
Carl and the Passions – "So Tough". Dennis wrote and produced two songs – "Steamboat" and "Only with You" – on their next album,
Holland (1973). A third song, "Carry Me Home", was left off the record. The cover of their 1973 live album,
The Beach Boys in Concert, depicts only Dennis onstage, although the album itself contains none of his songs.
Pacific Ocean Blue Wilson's onstage antics (including
streaking) occasionally disrupted the Beach Boys' live shows. He continued recording for his forthcoming solo album at the band's
Brother Studios facility in Santa Monica. In 1974, concurrent with the success of the greatest hits compilation
Endless Summer, Dennis returned to his role behind the drums. According to
Billy Hinsche, keyboardist for the Beach Boys' supporting band, it was during this year that Dennis co-wrote the lyrics and modified part of the melody of "
You Are So Beautiful" while attending a party with
Billy Preston. Hinsche said, "I was there that night, and I would not dispute that Dennis had a hand in writing 'You Are So Beautiful,' and that's the reason we would do it in concert." By 1977, Dennis had amassed a stockpile of songs he had written and recorded while factions within the Beach Boys became too stressful for him. He expressed, "If these people want to take this beautiful, happy, spiritual music we've made and all the things we stand for and throw it out the window just because of money, then there's something wrong with the whole thing and I don't want any part of it." Despite Dennis claiming the album had "no substance",
Pacific Ocean Blue received positive reviews and later developed status as a
cult item, ultimately selling nearly 250,000 copies. The album remained largely out of print between the 1990s and 2000s.
Bambu Pacific Ocean Blue follow-up,
Bambu, began production in 1978 at Brother Studios, with the collaboration of then Beach Boys keyboardist and Dennis' close friend
Carli Muñoz as songwriter and producer. The first four songs officially recorded for
Bambu were Muñoz's compositions: "It's Not Too Late", "Constant Companion", "All Alone", and "Under the Moonlight". The project was initially scuttled by lack of financing, Dennis' physical and mental decline due to
alcoholism and severe
drug abuse, which stemmed from his severe economic and marital problems at the time, and the distractions of simultaneous Beach Boys projects.
Bambu was officially released in 2008 along with the
Pacific Ocean Blue reissue. This material was also released on vinyl in 2017, without
Pacific Ocean Blue, for Record Store Day. Two songs from the
Bambu sessions, "Love Surrounds Me" and "Baby Blue", were lifted for the Beach Boys'
L.A. (Light Album) (1979). Dennis and Brian also recorded together apart from the Beach Boys in the early 1980s. These sessions remain unreleased, although they are widely bootlegged as
The Cocaine Sessions. ==Final years==
