Who are aespa?

aespa (에스파) are a four-member girl group under SM Entertainment: Karina, Giselle, Winter and Ningning. In an announcement of 2 November 2020, SM Entertainment explained the name as ‘æ’, standing for “Avatar X Experience”, joined to the English word “aspect”, meaning two-sided. The same announcement set the debut single ‘Black Mamba’ for 6 p.m. on 17 November.

CBS Nocut News reported on 29 October 2020 that aespa were SM Entertainment’s first new group in four years, since NCT in 2016, and its first girl group in six, since Red Velvet in 2014. The four members were introduced one a day ahead of the debut: Winter on 27 October, Karina on the 28th, Ningning on the 29th and Giselle on the 30th.

From the debut the group came with a world-view in which each member is linked, through a “SYNK”, to her own avatar in a virtual world, called ae-aespa. The official fan club is named MY. SM Entertainment used that name in its report of the third-anniversary fan meeting on 20 November 2023, and the Japanese official fan club runs under the name MY-J.

From the debut single to four mini albums

SM Entertainment’s album notes, carried on Bugs, describe the lyrics of ‘Black Mamba’ as a chase after the being that disrupts the link between the members and their avatars, ‘ae’. ‘Next Level’, released on 17 May 2021, follows a journey into the wilderness, KWANGYA, to find it, and Billboard put the song on its 25 best K-pop songs of 2021 that December.

The first mini album, Savage, released on 5 October 2021, was the group’s first physical record, and Idology named it one of its ten albums of the year. The second, Girls, came out on 8 July 2022; the album notes say its title track tells the last story of the world-view’s first season. Two weeks earlier came ‘Life’s Too Short’, the group’s first English single, which they had performed at Coachella in the United States in April 2022, before its release.

With the third mini album, MY WORLD, on 8 May 2023, the world-view entered its second season. According to the album notes, the pre-release song ‘Welcome To MY World (Feat. nævis)’ calls their helper, nævis, into the real world. The fourth mini album, Drama, followed on 10 November that year.

Two full-length albums

The first full-length album, Armageddon, came out on 27 May 2024, three years and six months after the debut, with two title tracks: ‘Armageddon’ and ‘Supernova’, released two weeks earlier. When Billboard put ‘Supernova’ on its 25 best K-pop songs of 2024 on 7 December, it noted that the song had reached number one on the Billboard South Korea Songs chart and spent 25 weeks on the Billboard Global 200. The fifth mini album, Whiplash, followed on 21 October 2024.

In 2025 came the single ‘Dirty Work’ on 27 June and the sixth mini album, Rich Man, on 5 September. Billboard noted that aespa received the Group of the Year award at that year’s Billboard Women in Music. Shortly before the release, Karina told NME that ‘Rich Man’ is “not about material wealth, but about self-confidence and believing in yourself”.

The second full-length album, LEMONADE, came out on 29 May 2026. According to The Korea Herald, it entered the Billboard 200 at number nine, the group’s third top 10 after Girls and MY WORLD. The Korea Economic Daily reported on 11 June that its cumulative sales on the Circle Chart had passed 1,037,190 copies, making it the eighth aespa album to pass a million. The chart run after the release is covered in a separate story.

Songs that came from the stage first

aespa have a habit of releasing songs they first sang in concert. The members’ four solo songs from the second concert came out on 9 October 2024 as SYNK : PARALLEL LINE, and the four solos from the third concert, at Seoul’s KSPO Dome in August 2025, came out on 17 November as SYNK : aeXIS LINE. The album notes for both say that every member took part in writing the lyrics or the music.

The group’s first unit songs, ‘Serenade’ by Karina and Winter and ‘Lollipop’ by Giselle and Ningning, were first sung at the Tokyo Dome on 25-26 April 2026 and released on 9 August as SYNK : aeXIS LINE (2026). Xports News reported that 94,000 people came to the two Tokyo Dome shows.

In Japan the group debuted on 3 July 2024 with the single Hot Mess, and released their first Japanese mini album, KISS N TELL, on 24 July 2026. On 2 August 2026 they played Lollapalooza Chicago in the United States for the first time. Five days later, on 7-8 August, they opened their fourth world tour, ‘2026-27 aespa LIVE TOUR - SYNK : COMPLæXITY’, at the Gocheok Sky Dome in Seoul, to 35,000 people across the two nights; the tour runs to 25 regions.
