News flash: You've been backing that 'thang' up for two decades.

In less than a week, the cultural phenomenon known as 'Back That Azz Up' will turn twenty years old. The Cash Money Records single that introduced New Orleans bounce music to the world is one of the few songs that still has the same effect today as the day it was released.

That date was February 24, 1999, and legendary producer Mannie Fresh was the man behind the track that still sends partygoers running to the dancefloor when they hear those iconic strings. He recently sat with Deconstructed to literally break down the record, beat by beat, explaining how created the instant classic.

We plan on doing something special on air to commemorate the 20th anniversary, but until then, enjoy this incredible piece of music history that we've celebrated since "the 99 & the 2000."
