A bio on Jones' website says he was born in New Orleans, but he relocated to Houston after Katrina. He then caught the attention of Houston rappers, including Trae Tha Truth and Mike Jones.

"Rest easy homie," Trae Tha Truth wrote on Instagram.
He went on to be mentored by rapper Akon and eventually signed with Birdman's Cash Money label in spring 2017.
Although his music features New Orleans sounds, he also paid tribute to Houston with the single "We Rollin'" for the support he received in the city.
Houston rapper Bun B posted a photo on Instagram about Young Greatness with the caption, "Woke up to another phone call I didn't wanna get. Another young brother shot down in the street. Prayers up for @younggreatness7."

Keisha Nicole at 97.9 The Box has interviewed Jones in the past. She told ABC13 one of Jones' friends gave him the nickname Young Greatness and he felt obligated to live up to that expectation.
"He was just grateful and so full of life and energy and just wanting to do really well in the game," she said.
His biography notes that he planned to release new music under his own New Orleans-based label, Mile High Music Group.
