Mamamoo

Mamamoo (; commonly stylized in all caps) is a South Korean girl group formed and managed by RBW. The group is composed of four members: Solar, Moonbyul, Wheein, and Hwasa. Known for their strong live vocals, harmonies, and writing much of their material, they are recognized as one of the premier girl groups in K-pop. They are highly regarded in the industry for their talent and ability to cross multiple genres with their music; from retro, jazz, and R&B concepts in their early years to more contemporary hip-hop, as well as emotional ballads. Since their debut in 2014, they have been noted for challenging conventional beauty standards, breaking gender stereotypes, and conducting themselves in ways that most typical K-pop stars do not.

Mamamoo officially debuted on June 18, 2014, with their first extended play (EP) Hello, featuring the lead single "Mr. Ambiguous". Their debut was considered by critics as one of the best K-pop debuts of 2014. Mamamoo rose to domestic fame in 2015 with their single "Um Oh Ah Yeah" which became a sleeper hit and peaked at number three on South Korea's Gaon Digital Chart. Combined with their many appearances and victories in the popular music competition program Immortal Songs, this launched them into mainstream recognition with the public. Their following release of "You're the Best" (2016) from their debut studio album Melting, proved to be a commercial success, and dominated at least eight major music sites upon release, further cementing their popularity and growing momentum. In 2017, they made a splash on the international scene with their fifth EP, Purple. Its lead single "Yes I Am," earned them their first number one on the Billboard World Albums chart.
