Rare (Hozier)

Anna is a 20-year-old famous cellist suffering from hyperthymesia, a rare medical condition which gives her the ability to visually remember everything. Her mind can easily recall specific events from the past, more or less pleasant, making it a constant chaos in which every single image triggers another hundred and each one of those, another hundred and so on until she blacks out, falling into an endless void of memories, fragments and glimpses, disorganized heaps of recollections a normal person would easily and naturally forget.
During a short 'daydreaming session', she meets a pretty straightforward tall curly-haired Irishman who asks her to join his band. What?!
