MAMAMOO showcase powerhouse vocals in teaser for anticipated pre-single

Excited for the promised pre-single ahead of MAMAMOO's official comeback?

The group surely is too as they dropped a teaser picture and video just today, showing the starkly different image they will be showing from their former quirky, bubbly, and bright one.  Here, they showcase their powerhouse vocals with a stylistically done discordant sound and intense vocalizing - all in black and white.

They sound as amazing as ever.  Stay tuned for the release on January 29!
