History
2020: Formation, debut, and 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.[1] 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.[2]
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.[3] Their cover was well received by the public and Lee Soo-man, which eventually prompted the creation of their subunit.[4] They also had several performances together during SM Town Live Special Stages.[5]
On July 6, Red Velvet – Irene & Seulgi released their debut extended play Monster, which contained six tracks, including the singles "Monster" and "Naughty".[6] With the release of their debut album, they became the best selling female sub-unit in South Korea in 2020.[7] The duo made their debut performance on July 10 on Music Bank.[8] From July 8 to September 8, the duo also starred in their own reality show, a spin-off of their group's Level Up Project!.[9] On August 18, 2020, Irene & Seulgi appeared and performed at Time 100 Talks, a live event series wherein global leaders talk about innovative solutions to urgent global problems, and encourage cross-disciplinary action among stakeholders.[10] Before their performance of "Monster", they also offered a message of appreciation and support to the frontliners during the COVID-19 pandemic.[10]
2025–present: Tilt
In 2025, SM Entertainment confirmed that the duo would be releasing new music in May of that year.[11] On April 14, they announced their first Asia tour, Balance, kicking off in Seoul on June 14.[12] On May 7, SM Entertainment announced that the duo's second extended play Tilt would be released on May 26, with the lead single of the same name.[13]
