Violin Concerto No. 1 -- Philip Glass

From Wikipedia:

The work was composed with Glass's father, Ben, in mind, despite the latter's death some sixteen years earlier: "I wrote the piece in 1987 thinking, let me write a piece that my father would have liked [...] A very smart nice man who had no education in music whatsoever, but the kind of person who fills up concert halls. [...] It's popular, it's supposed to be — it's for my Dad."
