Titled after her family name, the song serves as an ode to her family. The album opens with the song " The Grants".

Produced by Del Rey with frequent collaborator Jack Antonoff, Mike Hermosa, Drew Erickson, Zach Dawes, and Benji, the album features guest appearances from Jon Batiste, SYML, Riopy, Father John Misty, Bleachers (led by Antonoff), and Tommy Genesis. Del Rey called the creation of the album "totally effortless", saying that she wanted the music to have "a spiritual element". The album is in contrast with Del Rey's traditional approach of "world-building", found in her other work, such as in Norman Fucking Rockwell! (2019). Composition ĭid You Know That There's a Tunnel Under Ocean Blvd includes influences of 70s piano pop, hip hop, dance, gospel, folk, trap, soul, and psychedelic music.

Towards the end of production, Del Rey brought in previous collaborator, Jack Antonoff, which she revealed was when she felt she was making an album. Del Rey would hear him play and ask to record to the melody. She began working with Mike Hermosa, a prominent collaborator on the album, when he would visit Del Rey and play her piano. ĭel Rey eventually began working with other collaborators. The first song written for the album, "Fingertips", was recorded this way, with no prior writing. She would sing whatever came to her mind into the voice notes application on her phone, later "sending those really raw-sounding" recordings to composer Drew Erickson, who would add reverb to her vocals, as well as an orchestral instrumental.

Del Rey departed from her signature colorful language and world-building, found in her other work, in favor of a conversational style, relying on a process she named "automatic singing". Work on the album started shortly after the release of her eighth studio album, Blue Banisters, in October 2021. The release of " The Grants" followed one month later on March 14, 2023. Three singles preceded the release of the album: the title track was released as the lead single on December 7, 2022, while " A&W" was released as the album's second on February 14, 2023. Upon release, Did You Know That There's a Tunnel Under Ocean Blvd received generally positive reviews from music critics, many of whom felt the lyrical style depicts a mature Del Rey. The album features production by Del Rey, Mike Hermosa, Jack Antonoff, Drew Erickson, Zach Dawes, and Benji and includes collaborations with Jon Batiste, Bleachers, Father John Misty, Tommy Genesis, SYML and Riopy.
