The film follows the band Slowdive as they come up in the flourishing Thames Valley shoegaze scene and chronicles the making of their classic album Souvlaki. It features interviews with all of the band members as well as Creation Records' Alan McGee, producer Chris Hufford, and engineer Ed Buller.

BEAUTIFUL NOISE is an in-depth exploration of a music movement in the late twentieth century, a fascinating period when some innovative musicians mixed guitar noise into conventional pop song structures while maintaining a philosophy of letting the music speak for itself. Although many of the people interviewed are notoriously press shy they have opened up about their music and experiences from over 20 years ago, how they defied the rules and became sonic innovators that have inspired so many.
