Heartbeats - 7/7/19

My parents recently moved house and while going through all of their belongings came across a number of outdated recording media - cassettes, reel to reel tape, minidiscs, even a couple of microcassettes - which they gave to me to see if I found anything interesting. Of the cassettes, most of them were mixtapes and practice tapes for my mother (she's a classical singer), but this one stood out to me. One side is of when my mother was pregnant with my older sister, and the other side was recorded three years later when she was pregnant with me. Maybe these recordings only mean something to me but I thought they were neat.
