Charles Manson sessions (1968) According to
Charles Manson, the musician later convicted for
several murders, he took part in "a pretty fair session, putting down about ten songs" at Brian's home studio. Band manager
Nick Grillo stated that there were approximately "a hundred hours" of Manson's music recorded at the studio. In 1971, Mike Love told
Rolling Stone that the band still possessed "several 8-track tapes of Charlie and the girls that Dennis cut." In
Vincent Bugliosi's 1974 book
Helter Skelter, he reported that Dennis claimed to have destroyed the tapes, because "the vibrations connected with them don't belong on this earth." While the group denied that tapes of these sessions exist – with co-productions by
Carl and Brian (not Dennis as had often been stated) – engineer
Stephen Desper averred that they do, believing at the time that Manson's material was "pretty good... he had musical talent." Asked about the existence of those tapes in 2021, Brother Records archive manager
Alan Boyd declined to offer a comment.
A World of Peace Must Come (1969) A World of Peace Must Come is an album by poet
Stephen Kalinich that was produced by Brian Wilson in August and September 1969. It was officially released on October 6, 2008.
Friends remake (1970s) In the early 1970s, Wilson rewrote and rerecorded some cuts from the
Friends album. Of the songs rerecorded, it was only the semi-instrumental "Passing By" that was eventually released on the compilation album

The Cocaine Sessions (1981) "The Cocaine Sessions" (or "The Hamburger Sessions") refers to a sporadic, collaborative recording session conducted by Brian Wilson in 1981 at musicologist Garby Leon's beach house. Recordings were made for songs entitled "Yeah", "Oh Lord", "City Blues", "I Made a Prayer" or "I Search This World", "Why Don't You Tell Me Why" or "You've Been", and "I Feel So Fine" (including a snippet of a cover of
the Ronettes' "
Be My Baby") on bootlegs as well as a rendition of "
Heroes and Villains" with at least one other song, a ballad entitled "Bobby, Dale and Holly", having yet to surface officially or otherwise. The titles popularly assigned to the sessions derive from an anecdote that Dennis Wilson gave Brian
cocaine and
McDonald's hamburgers in exchange for his participation (which was dramatized in a scene of the 1990 television movie
Summer Dreams: The Story of the Beach Boys) with Leon preferring "The Hamburger Sessions" as he claimed no cocaine was involved in the sessions themselves. Another song written by the two Wilsons and Leon, "Stevie", was later recorded at a studio as Dennis' final production before he died in 1983. Sequences that would later form the "
Rio Grande" suite on
Brian's 1988 debut solo album reportedly also came from the collaboration. "I Made a Prayer" was reworked into "This Isn't Love" and recorded by actor
Alan Cumming for the 2000 film
The Flintstones in Viva Rock Vegas soundtrack. Brian later rerecorded "City Blues" (without co-writing credits of Dennis and/or Leon) featuring
Eric Clapton for his 2004 album ''
Gettin' In Over My Head. "Stevie" was allegedly written about Stevie Nicks of Fleetwood Mac and was considered for the 2013 box set Made in California''.
The Wilson Project (1986–87) "The Wilson Project" refers to sessions conducted between Brian and
Gary Usher from June 1986 to July 1987 before the recording of Brian's first solo album. The name derives from Stephen McParland's book
The Wilson Project, drawn from journals and tape diaries kept by Usher from the period.
Sweet Insanity (1990–91) Sweet Insanity is an unofficial Brian Wilson solo album that would have followed his first. It was rejected twice by
Sire Records due to the inclusion of a rap song entitled "
Smart Girls" and certain lyrics written by Wilson's conservator
Eugene Landy. ==Bootlegs==
