Rehearsing for the Billboard Music Awards last month, Sounds of Blackness had finished the fourth or fifth take of their hit "Optimistic." Timing had to be precise for this network telecast. No room for error.
Before choir director Gary Hines could say "Let's do it again, like Mavis Staples says," he spotted something amiss in the circle of 20 singers.
"Stand by," he called out as he noticed tenor Steve (Smokey) Dinkins getting misty-eyed.
"Smoke, this has been a song that means a lot to me," Hines said. "It helps me out." Then he told the group that Dinkins recently lost his mother.
"Sorry," Dinkins blurted, wiping his face with a towel.
"That's the real deal," said Hines, noting how Dinkins had been moved by this song of hope in a crisis. "The Grammys are great, but this is the real deal."
That's Hines — part teacher, part preacher, part psychologist, part father, part coach, part activist, part historian, part musical master, part drill sergeant.
For 50 years, he has led Sounds of Blackness, building them from a student choir at St. Paul's Macalester College to three-time Grammy winners who have raised their voices on five continents and worked with everyone from Aretha Franklin to Elton John.
