Pip Piper's new documentary The Vinyl Revival and the Shops That Made it Happen, based on Graham Jones's book of the same name, is a love letter to an industry that's in the process of an unbelievable comeback.

Compared to the bleakness of Last Shop Standing, Piper's previous film on the fate of record stores, this documentary feels celebratory. It features a mix of shop owners, including a brief nod to Cowley Road's very own Truck Store, and collectors - some experienced and others just starting out. They're a diverse bunch but what links them is the wide-eyed, excited look they give to camera when they start talking about vinyl.

Phil Barton of Sister Ray Records in Soho describes the change in the industry between the two films as 'Lazarus' like. Resurrected from what seemed like certain death, there are now more record shops opening every year than closing. Where Last Shop Standing saw hand-written closing down notes in dreary windows, The Vinyl Revival presents toothy grins, popped champagne and celebratory vinyl-themed tattoos.

But behind the veneer of excitement and enthusiasm lies a sense of dread. Record stores may be experiencing a boom at the moment, but the old guard of shop owners know all too well what can happen when public interest sways. Independent shops are facing a constant battle against Direct to Consumer marketing and chain supermarkets dipping the most cursory of toes in the vinyl trade.

What revives the film's optimism is the introduction of up-and-coming band Cassia, signed to Distiller. The drive and excitement of this trio to release their debut album on vinyl reassures us that the dogged determination of shop owners, producers and collectors is worth it. Seeing the boys find and hold the finished album in their local record store affirms every claim the film makes about the beauty and importance of vinyl. It may be precarious, but it's definitely precious.

Head to Truck Store on Cowley Road or Rapture in Witney to fall back in love with collecting music. There are still screenings of the film in Exeter, North Yorkshire, Liverpool, Emsworth, Cambridge, Birmingham, Cinderford and Edinburgh, or you can download the film by purchasing the Distiller Vinyl Revival album here.
