Mamamoo – South Korean k-pop, jazz, retro, and R&B band
The lineup of Mamamoo includes four young women, Solar, Wheein, Moonbyul, and Hwasa. The creation initiative and the funding of the girl band belongs to the Seoul company RBW (ex -WA Entertainment).
Since January 2014 and until its official debut in June, the group assisted other musicians to record different tracks. Together with Bumkey, the musicians released a single "Don't Be Happy" in January 2014. A month later, they collaborated with K. Will to present "Peppermint Chocolate". The single climbed to the 11th spot of South Korea Gaon Digital Chart. In May 2014, together with a rap duo Geeks, the band recorded a new single, "HeeHeeHaHeHo".
In June 2014, the musicians debuted with the single “Mr. Ambigous”, which became a part of their first EP, Hello. To promote the track, the band recorded a music video, which featured the work of such popular artists as Baek Ji-young, Jonghyun, Bumkey, Wheesung, Jung Joon-young, and K.Will. Besides the single, the EP featured such songs as "Heeheehaheho", "I Do Me", "Baton Touch", "Peppermint Chocolate", and "Don't Be Happy". The album climbed to the 16th position of South Korea Gaon Albums Chart, which was an excellent result for a young group. At that time, many organizers tried to book Mamamoo for private events.
