Resident Pianos is an article in Resident Evil Recollections. It was uploaded on 21 December 2015.
At the start of Resident Evil 6, Leon and Helena are searching for Liz, the daughter of one of the survivors they are with.
At a certain point you can hear Chopin's Nocturne No.2 playing from the stage, and many of you will no doubt be reminded of the Moonlight Sonata from the very first Resident Evil. These aren't the only examples of pianos cropping up in Resident Evil either.
The group finally finds Liz in the music room, no doubt it was her who was playing. She seems to be a good player too, better than Rebecca at any rate...
