Hyun-ah & Dawn will release their first EP [1+1=1] on various online music sites at 6 p.m. on September 9th and release the music video for the title song "PING PONG."

[1+1=1] is an album that unfolds things that can only imagine in dreams. Hyun-ah & Dawn, who became one, not two, expressed honest and unconventional music in various colors.

The title song "PING PONG," in which Hyun-ah & Dawn jointly participated in the lyrics and composition, is a Mumbaton dance song with an intense lead sound consisting of Mumbaton rhythm and 808 bases. It features a lover in love in cute and popping lyrics as if a table tennis ball was moving back and forth.

Music videos and performances also point to watch. The addictive couple's group dance and the dance break that emphasizes Hyun-ah & Dawn's individuality will blend with the kitsch visuals to provide viewers with a variety of fun.
