"She was unique. And those type of iconic performers are special. They don't come around that often," said Arny Granat, co-founder of Jam Productions.

In the 1970s, Turner took to the stage like a fireball, Granat recalled.
"She gave it all on stage," he said. "She was so energetic and you just wanted to look at her and just keep looking. You couldn't take your eyes off of her."
Granat spent time on the road with Turner throughout the early decades of her career. At the time he helped to promote and produce a tour that launched a legend.
"Tina was one of the acts we took on the road," he said. "The reception everywhere was awesome, and she was freaking Tina Turner."
"When she hit that stage, right, she made everybody work," said Marshall Thompson, singer and founder of the Chi-Lites.
Thompson said touring with Turner meant turning it up.
"Because when she gets through with that stage, you better work. If not, you might get booed off the stage," he said.
Granat, having produced thousands of acts throughout his career, still can't find the words to describe what made Tina, Tina.
"She just moved like no one else did. She was one of those, you've just got to see it. You can't explain it," he said. "She passed away as a human being, so to speak, but her legacy is going to live on forever."
Turner died Wednesday at age 83 in Switzerland after a long illness.
