My GF was a photographer at a Secret Cinema event with Laura Marling that took place in London. She had to take some promo pictures, so they met in one of the event rooms [1] for the photoshoot. After just a few pictures they were done and instead of wrapping up, Laura started to perform one of her songs.

Not the same scale as Bob Dylan concert, but still a concert for one. A kind gesture, unconditional, free, ephemeral, but leaving a life lasting memory.
