The Postal Service: Everything Will Change is a profoundly intimate and emotive concert film documenting the two-night, sold-out performances by the celebrated band, The Postal Service, at the Greek Theatre in Berkeley, California, in 2013. The film is a beautiful encapsulation of a momentous event in the history of this influential electronic indie-pop band that initially was intended as a side project.

The movie opens with the backstory of The Postal Service, named after the method by which its two members – Ben Gibbard of Death Cab for Cutie and producer Jimmy Tamborello – communicated and exchanged music files while creating their heart-rending album, "Give Up". This poignant duet created and released the album by sending audio files to one another through the US Postal Service, hence the band's name. This side project turned into a massive hit, and the film celebrates the 10 year anniversary of the seminal album's release. The story of the band is correspondingly brought to life with old footage and interviews woven in between concert clips, exploring the band's backstory, interesting beginnings, and extraordinary rise to fame.

At the crux of the film is a spellbinding concert experience, ranging across the band's iconic tracks, blending both energetic and intimate performances. The film is awash with resounding live performances of songs from their critically acclaimed album, such as "Such Great Heights," "The District Sleeps Alone Tonight," and "We Will Become Silhouettes," illuminating the band's unique ability to craft music that resonates across generations.

Besides Ben Gibbard and Jimmy Tamborello, the film also follows Jenny Lewis (Rilo Kiley), and Laura Burhenn (Mynabirds), who joined the band’s lineup for its reunion shows. Throughout the film, viewers get a peek into the chemistry and camaraderie among the band, including behind-the-scenes footage and interviews showing their interactions and reflecting their collaborative spirit, sensitivity, and vision. The camera doesn't just stay onstage but ventures into the wings, capturing the quiet moments between performances.

The film effectively communicates the band's unique atmosphere - a perfect balance between melancholic melody and upbeat electronics, capturing the sound, energy, and excitement in the grandeur of the Greek Theatre. The performances have an ethereal feel to them, reflective of the band's wistful and emotive style, yet filled with a sense of joy and electricity that permeates throughout the audience.

This documentary-style concert film provides fans and new listeners alike with a window into The Postal Service's creative process, as well as their genuine affection for the fans worldwide. It presents an uneasy question of whether these two-night performances were the band's final farewell or a revivification, a question left tantalizingly open-ended in the film.

Directed by Justin Mitchell and presented in vibrant cinematography, the movie strikingly illuminates the band's dynamic aura and the lush spectacle of their live performances. The choice to cut between live performances and intimate backstage moments gives the film an intimate feel that separates it from standard concert films.

Beyond the music, the film explores the broader cultural impact of the band, the album's legacy, and its place in early indie music of the 2000s. From hardcore fans expressing their love for the band, a mesmerizing visual background to the band's music, and tracking the influence of The Postal Service, the film stands as a testament to how art - even unintentionally - can make a historic and emotional impact.

In conclusion, The Postal Service: Everything Will Change serves as an elegy to an era, even while it celebrates the band's unique music and its enduring impact. It is an essential watch for fans of The Postal Service, indie pop culture enthusiasts, music historians, and everyone with a penchant for nostalgic, electro-pop melancholia.
