From the looks of dit, the theme of the video takes a blast to the past into the '70s for a disco-inspired set and costumes with the return of bell bottom jean! Fear not as the bell bottom won't seep into the rest of the K-Pop world -- just this MV.�

The fun, fast-paced beat of A.N.D.S's new single lends it a disco-vibe with a memorably catchy melody.�

Listen to the song in the brief teaser above, and watch out for the full MV when it drops this July 29!�
