Quentin Tarantino's Once Upon A Time In Hollywood

The Once Upon a Time in Hollywood soundtrack is a meticulously curated, era-immersive collection that functions like an audio time machine to 1969 Los Angeles. Crafted by Quentin Tarantino and music supervisor Mary Ramos, it blends popular rock ‘n’ roll, obscure gems, vintage radio jingles, and Western film score snippets to recreate the mood and textures of the era  .

From the moment Roy Head & The Traits’ “Treat Her Right” fires up the opening scene, the soundtrack sets a sun-drenched yet subtly ominous tone  . It weaves in iconic tracks like Deep Purple’s “Hush,” Bob Seger’s “Ramblin’ Gamblin’ Man,” and José Feliciano’s haunting rendition of “California Dreamin’,” alongside lesser-known vinyl treasures and KHJ-AM radio jingles, making the music an active atmospheric force  . The layered radio clips and commercials evoke Tarantino’s childhood listening experiences, grounding the film in its historical period  .

Critically acclaimed for its narrative integration, Pitchfork described it as “an undeniable, oft-disquieting mixtape of golden-age rock ’n’ roll, radio DJ patter, and period-specific commercials,” which ties the fictional story to real 1960s Hollywood  . TIME notes how the music underscores the film’s tension between Hollywood’s idyllic façade and its darker undercurrents, particularly in scenes linked to the Manson Family
