"Good Vibrations" were recorded between April and June. Brian then forwent additional instrumental tracking until early September, when it was decided to revisit the song's bridge section and apply Electro-Theremin overdubs. According to Brian's then-new friend David Anderle, during an early stage, Brian considered giving "Good Vibrations" to one of the black R&B groups signed with Warner Bros. Records such as Wilson Pickett, and then at Anderle's suggestion to singer Danny Hutton. He thought about abandoning the track, but after receiving encouragement from Anderle, eventually decided on it as the next Beach Boys single. In the meantime, he worked on writing and recording material for the group's forthcoming album, Smile. The first Beach Boy to hear "Good Vibrations" in a semi-completed form, other than Brian, was Carl. Following a performance with the touring group in North Dakota, he remembered: "I came back up into my hotel room one night and the phone rang. It was Brian on the other end. He called me from the recording studio and played this really bizarre sounding music over the phone. There were drums smashing, that kind of stuff, and then it refined itself and got into the cello. It was a real funky track." In 1976, Brian revealed that before the final mixdown, he had been confronted with resistance by members of the group, whom Brian declined to name. The subject of their worries and complaints was the song's length and "modern" sound: "I said no, it's not going to be too long a record, it's going to be just right. ... They didn't quite understand what this jumping from studio to studio was all about. And they couldn't conceive of the record as I did. I saw the record as a totality piece." The vocals for "Good Vibrations" were recorded at CBS Columbia Square, starting on August 24 and continuing sporadically until the very last day of assembly on September 21. The episodic structure of the composition was continuously revised as the group experimented with different ideas. Brian remembers that he began recording the "bop bop good vibrations" parts first, and that he came up with "the high parts" a week later. Mike Love recalled: "I can remember doing 25–30 vocal overdubs of the same part, and when I mean the same part, I mean same section of a record, maybe no more than two, three, four, five seconds long."
