Lucy is a 2014 science fiction action thriller film directed by Luc Besson and starring Scarlett Johansson. The film follows the story of Lucy, a woman who is forced to become a drug mule for a group of gangsters. When she is accidentally exposed to a powerful drug, her intelligence is amplified to superhuman levels, and she begins to unlock the full potential of her brain.

The film’s theme song, “Sister Rust,” is performed by Damon Albarn, lead singer of the bands Blur and Gorillaz. The song is a haunting and atmospheric ballad that perfectly captures the film’s themes of transcendence and evolution.

The song’s instrumentation is also notable, with its sparse piano and strings accompaniment. This creates a sense of intimacy and vulnerability, which perfectly complements the film’s more emotional moments.
