According to Brian, many of the musicians who were present at the 'God Only Knows' sessions claim that those sessions were some of "the most magical, beautiful musical experiences they've ever heard." According to Brian there were 23 musicians present during the 'God Only Knows' sessions, though only 16 are credited as being present on the actual take that was used for the final song. At the time, 23 musicians was an astounding number of musicians for a pop record. All the musicians played simultaneously, creating "a rich, heavenly blanket of music."
The vocal track was recorded between March and April 1966 at
Columbia Studios, Hollywood, California, with the session engineered by
Ralph Balantin and produced by Brian Wilson. The song features three voices on the track. Carl Wilson is featured on lead vocals, with Brian Wilson and Bruce Johnston backing him. Bruce Johnston explained that, "The really cute thing is that at the end of the session, Carl was really tired, and he went home. So Brian ... remember, this was 8-track, so, he now has these extra tracks at his disposal. But there were just the two of us. So in the fade, he's singing two of the three parts. He sang the top and the bottom part and I sang in the middle."
[3] Brian used the production technique of double-tracking Carl's voice, so that his voice is simultaneously singing the same part twice, to give the vocal a fuller and richer sound; Brian Wilson used this technique often during the recording of
Pet Sounds.
