Remember when someone used the word “mixtape” and they actually meant a tape? Depending on your age, you might not. A new documentary chronicles the reign of this medium and its fascinating niche revival. “Cassette: A documentary mixtape” is an in-depth look into an audio format that once commanded the attention of all music lovers. Unlike vinyl, this configuration empowered the user to customize and share tangible soundtracks of their tastes, moods, and sonic passions. Relive the era when dual decks, Walkmans, and boomboxes were ubiquitious, and cassettes ruled the world. -Israel Vasquetelle
