“Marvin Gaye: What’s Going On” (9 p.m., PBS): He was shot to death the day before

“Marvin Gaye: What’s Going On” (9 p.m., PBS): He was shot to death the day before his 45th birthday on April 1, 1984 — by his own father. Everyone remembers the death of Marvin Gaye. And everyone remembers the music he made. But the life he lived isn’t nearly as familiar. A new “American Masters” portrait, “Marvin Gaye: What’s Going On,” aims to fill in the gaps. Gaye’s early hits included “I Heard it Through the Grapevine,” as well as romantic duets with Tammi Terrell, who died from a brain tumor in 1970 after collapsing in his arms on stage during a concert. This tragedy drove him to write and record his seminal album “What’s Going On” (1971). A decade later, “Sexual Healing” was his final hit. Along the way, he battled depression and substance abuse. Adding to his burden was the stormy relationship with his father, a traveling minister and strict disciplinarian at whose hands he died after an argument. The documentary hears from Nick Ashford, Mos Def, Berry Gordy, Gladys Knight and Smokey Robinson, among others.
