That closeness is felt throughout "Rocket Power," and the second half of the title track might be the most affecting moment of all. In the final verse, the trap production drops, making way for simple balladic moment. "Mama, I can't sleep / I lost my bro, aw, this just a dream / Eternal nightmares / I don't know 'bout how we got here / I wan' go far, but I don't know where," Quavo sings. "But when I go, I ain't got no fear / I bet my nephew gon' be right there / I see my niece and nephew cry tears / I told 'em, "Wipe your eyes 'cause unc' here."

It's a potent meditation on grief — steps of depression, denial, and acceptance rolled into a few seconds. For listeners, it is an emotionality amplified by the fact that this is the sound of Quavo in the studio for the first time since losing both a family member and his closest collaborator.

But would it be a Quavo release if it didn't end on an empowering note? The closer "Greatness" is a horn-led celebration. "This how legends was born / Greatness / I couldn't do it without the greatest group in the world / Hmm, greatness / I couldn't do it without the greatest nephew in the world," he raps.

"Rocket Power," was scheduled to be released two weeks ago, but was delayed to "run some more tests before the rocket is ready to launch," Quavo wrote on Instagram.
