The Beach Boys recorded a myriad of songs, instrumentals, and alternate versions of tracks that have never been officially released. Only recordings that have been reliably confirmed to have existed are listed here. Some of these tracks circulate on bootlegs, but many of the tapes have been lost since their creation.
This list is ordered chronologically, by recording date, and does not include non-substantial rehearsal tapes or jam sessions recorded by the group. Live recordings are included if there is no studio equivalent. Some tracks listed under certain album subheaders may not have been recorded for that particular album, but are listed as such simply to note the band's then-current album project at the time of recording.
A total of 28 songs were written and recorded for the album. Discounting the 2011 rerecording of "Do It Again", only twelve tracks saw release.
For historical interest, the following is a list of studio outtakes and live recordings that later appeared on Beach Boys compilation albums. It is partially adapted from Andrew Doe and Phillip Lambert.
Some of these releases are currently out of print. California Feeling 2 was a limited-edition CD offered with a 2015 issue of Endless Summer Quarterly, an unofficial Beach Boys fan/collector's magazine. Misc Tracks 1971 and 1972 Release were among several releases (the others not being listed here), most of which were briefly offered online (commonly through Bandcamp, YouTube, and/or AllMusic) and then quickly taken down, to preserve copyright under the 2013 European Union copyright extension legislation.
