Miller's estate emphasized the importance of releasing "Balloonerism" officially, especially given the existence of unofficial versions circulating online for years.

Accompanying the album is a film directed by Samuel Jerome Mason, which explores the transformative power of music through the journey of a group of friends navigating adulthood.

Both the film and the album are available on Prime Video and various streaming platforms, allowing fans to engage with Miller's work in multiple formats.

Musically, the album leans into neo-soul and jazz, characterized by dreamy, drug-influenced tones and abrupt changes in tempo and instrumentation.

Lyrically, Miller's work often reflects on themes of death, nostalgia, and personal experiences, as seen in tracks like "Excelsior," which includes poignant lines about childhood.

The lead single, '5 Dollar Pony Rides,' has already been released, showcasing Miller's reflective lyrics about past relationships.

The project, recorded in 2014, was confirmed by Miller's family in late 2024, underscoring its significance to the artist's legacy.

"Balloonerism" features 14 tracks, including notable songs like '5 Dollar Pony Rides' and 'DJ's Chord Organ' featuring SZA, as well as contributions from Thundercat and Miller's alter ego, Delusional Thomas.

This marks the second posthumous album from Miller since his passing in 2018, following the release of "Circles" in 2020.

Upon its release, the album quickly gained traction, trending No.1 on X (formerly Twitter), with fans praising its emotional depth and quality.

Mac Miller's highly anticipated posthumous album "Balloonerism" was released on January 17, 2025, alongside a short film.

The release was teased at the Camp Flog Gnaw festival in November 2024, where a trailer showcased the track "DJ's Chord Organ" featuring SZA.
