Mack 11 comes out the gate with a dope single, Back It Up making a great first impression on his artistry. Back it up is the ideal club banger, but also has the bass heavy trap rhythm produced by 808 Mafia. Back It up is for ladies in strip clubs, twerking on the gram or just a feel good song to turn up. Saint Millie graces a flattering hook & verse making the song memorable and catchy with lines like “treat shorty like a mixtape”. Mack 11 adds his twist acknowledging himself as a rookie, yet giving the song a southern feel, stunting & saying no matter how fresh, shorty gon back it up because of his swag & flare.
