Hawthorne, CA, subtitled Birthplace of a Musical Legacy, is the second anthology collection by the Beach Boys and released through Capitol Records. A double-compact disc, it was put together after the positive reaction to the Endless Harmony Soundtrack to give hardcore Beach Boys fans more rarities and alternate versions of well-known songs. The collection features spoken word tracks from different band members recorded throughout the 1990s during production of the Endless Harmony documentary, as well as a clip from a 1969 radio show. Home recordings dating back to 1960 and a backing track from 1973's "Sail On, Sailor" were also included. It never charted in either the United States or the United Kingdom, and it is currently out of print.

Endless Harmony Soundtrack is an anthology album of previously unheard material by The Beach Boys, originally released by Capitol Records in August 1998. Named for Bruce Johnston's song on the 1980 album Keepin' the Summer Alive, it was designed as a tie-in with the band's biographical documentary of the same name. The soundtrack was re-issued in March 2000 with some remixing and different artwork, while the original 1998 edition went out of print shortly thereafter.
