I’m using a few slices of this sample, originally from a Cellist playing on YouTube.
I don’t remember who is playing or what song is being played. I’m also having trouble relocating the YouTube video, but I don’t know for sure that it’s been removed.
Please let me know if you find the original. I believe I was searching for “cello” or “cellist”. If I remember correctly, the video is of a man, I’d guess over 50, playing the cello in a living-room.
