Music like Red Velvet - IRENE & SEULGI

Red Velvet – Irene & Seulgi (Korean: 레드벨벳-아이린&슬기; stylized as Red Velvet - IRENE & SEULGI) is the first sub-unit of South Korean girl group Red Velvet, formed by SM Entertainment in 2020. It is composed of members Irene and Seulgi. The duo debuted on July 6, 2020, with the extended play Monster.

On April 21, 2020, SM Entertainment revealed that Irene and Seulgi would form Red Velvet's first sub-unit. On the same day, it was announced that the unit would release their first extended play in June. The release of the mini album was later postponed on the grounds that it needed additional production on the album, in order to achieve a higher quality of music.

Before their debut as members of Red Velvet, the duo, as part of SR14G (SM Rookies 2014 Girls), notably performed a cover of "Be Natural", a song that was sung originally by S.E.S. Their cover was well received by the public and Lee Soo-man, which eventually prompted the creation of their subunit. They also had several performances together during SM Town Live Special Stages.
