The Booty-Shaking Anthem That Still Endures, 25 Years Later

Twenty-five hot summers ago, Juvenile threw out a command and booties everywhere have never been the same. That’s when “Back That Azz Up,” the second single from the New Orleans rapper’s album “400 Degreez,” was released and almost instantly became the national anthem of twerking — before the word even entered the American vocabulary.

Arguments can be made that the song is misogynistic, endearing or both. But the track — built around Juvenile hypnotically rapping the song’s title instruction, a raunchy verse from its producer, Mannie Fresh, and a syrupy outro from an ascendant, teenage Lil Wayne — has definitely proven to have staying power.

Juvenile, 49, initially doubted the song would succeed as a single, and it took a last-minute trip to Nashville’s Music Row to finish the recording. Ultimately, the song helped usher bounce music, the New Orleans branch of hip-hop featuring fast beats and call-and-response chants, into the mainstream while strengthening the South as an epicenter of hip-hop. In interviews, the artists and key figures behind the song explained how it all came to be. These are edited excerpts from the conversations.

JUVENILE I sung the “Back that Azz Up,” hook, probably half a year, about five, six months knowing that I was working on my album.

MANNIE FRESH I heard the lyrics first. I was just like, “You know what? This is already magical.” So the beat got to marry it.
