With nearly a century to cover, If These Walls Could Sing had the daunting task of giving justice to the history of the iconic Abbey Roads Studios. In 89 minutes, Mary McCartney outlines the studio’s history through archival footage and a stacked selection of artist interviews, popping only in random moments to organize the timeline. With the wide selection of artists, the film can feel scattered, as it jumps from classical music, to rock and roll, and to film scoring. The documentary doesn’t really go in-depth into how the studio developed its sound, but there are some interesting insights into certain tracks, like how the studio approached contracts, experimentation, different genres, and technology. While the film relies too much on nostalgia, it’s still an interesting tour based on the subject matter alone.
