Solar has new music on the way. MAMAMOO’s official account shared a coming soon poster for her single ‘나의 20대에게’ (roughly “To My 20s” in English; that’s kpop/fwd’s translation, since the poster only gives the Korean title), arriving November 12 at 6 PM KST. That’s 4 AM ET.

The title comes with a credit attached: Harmonica. 하림, meaning Harim plays harmonica on the track. The rest of the details, from the concept to any music video, haven’t been shared yet, so the poster is the first official look.

Keep an eye on MAMAMOO’s channels for more as the release gets closer. Until then, her music video for ‘EXIT’ is above.
