Permissive

Permissive is a movie starring Maggie Stride, Gay Singleton, and Gilbert Wynne. Suzy arrives in London with nowhere to stay and meets Fiona, a group who has settled into a relationship with Lee, a singer/bassist in a rock band.
When Suzy arrives in London to visit an old school friend, she is unwittingly plunged into the ruthless world of the 'groupie'. Fuelled by sex, drugs and jealousy, her new lifestyle fosters in her a cold, cynical instinct for survival. But tragedy is never far away. With its effective blend of gritty location work, brooding flash-forward devices, and a soundtrack by cult acid folk and prog rock legends Comus, Forever More - who also star - and Titus Groan, Permissive is a dark British counter-cultural artefact that's shot through with grim authenticity. As a bonus, this release also includes Stanley Long's ultra-rare Bread, a film which, whilst exploring the same cultural milieu as Permissive (and featuring its own bona fide cult British rock band, Juicy Lucy), takes a somewhat more lighthearted approach to its subject.
