"1979. My father had this on vinyl before I was born. I found it in a box he kept under the bed with other things he treated carefully. I didn't ask permission. I was maybe fifteen, running nowhere in particular, and Don't Stop 'Til You Get Enough came on and something in my legs changed. Like the ground was doing something. He made this album at twenty years old. Twenty. I think about that on bad runs, when the Charles River is grey and nothing is working. He was twenty and he made something that still does that to people's legs forty years later. I haven't told my father I found the record. Some things you keep."
