Both of those were very inspiring. I've been playing with recorded accompaniments for a decade and a half now, because (except for IET) I do not have a collaborative pianist with whom I can work. Almost all of my videos on my own YouTube channel were performed with a recorded accompaniment, albeit not as fancy as these; usually just a synthed version of the published piano accompaniment. These are several steps above that, and cheap at twice the price.
