“An homage to the surf music the Beach Boys helped make so popular, this song is certainly one directly from the depths of Gin Blossom Jesse Valenzuela’s heart,” (Songfacts). “Jesse’s original role with the Gin Blossoms was as lead singer. He switched to guitar with the introduction of vocalist Robin Wilson to the band. Yet he was – and is – one of the band’s most prolific songwriters. While some artists may have a rough time of it allowing someone else to sing their words when they themselves are perfectly capable of doing it, Jesse says it doesn’t bother him.”
InnerEarMedia‘s review of the band’s 2006 album Major Lodge Victory has this to say about “California Sun,” the album’s closing track: “The easy-to-the-ears pop of the Gin Blossoms is like a warm blanket surrounding you and keeping you safe. That blanket only gets warmed more by ‘California Sun’ as the sweet pop song brings this great album to an appropriate end. Gin Blossoms leave us with a folk/pop song that could’ve come straight from the 70s (Eagles, America, etc.) and it makes you smile.”
Starting in E major, a bridge at 2:03 begins with a vocal section but then settles into a guitar feature. We’re led into a key change at 2:49 with an emphatic, extended V chord in the new key of F major, complete with richly textured backing vocals echoing the Beach Boys’ style. At 3:00, the final chorus is firmly established in the new key.
