A computer parsing voice and instruments into a single midi track. It sounds really terrible, but hang in there to see if you can hear the “vocals” — who would have thought you’d ever hear a piano “singing” Piano Man? Fascinatingly freaky.
HT to my son for finding this. Some families have different definitions of quality time. For us today, it’s flopping on the couch with our laptops & sharing what we find. ❤
