Martina Pastori explores themes of class, isolation and loneliness in her video for London-based rock outfit High Vis, featuring Welsh movement artist Sem Osian. 

The video for Mind's A Lie begins with a jolt: a scene akin to recent turbulent events of unrest and violence in Britain. But writer/director Pastori endeavours to create a rounded portrait of a disaffected and disturbed working class young man, played by Osian, in the film shot in South London.

The song itself provided the jumping off point for the creation of Osian's character. In Mind's A Lie, High Vis frontman Graham Sayle says that he wanted to "look at how quickly negative habits can take control when you lack a positive or constructive outlet for your energy." And he makes clear that this is a situation caused by decisions made at government level.

"While the language of mental health provision has found fertile ground in the churn of social media, access to essential services has been decimated by the indifference of successive Tory governments," adds Sayle. "Further division has been stoked through governmental rhetoric and media scapegoating. Without adequate support in times of crisis, life can quickly spiral into an angry and isolated existence."

Pastori makes that political point by focussing entirely on Osian, as a very believable character caught in that spiral.
