LE SSERAFIM’s “BOOMPALA” is the title track of the group’s second studio album, “PUREFLOW” pt.1, which was scheduled for release on May 22, 2026, at 1 p.m. KST. SOURCE MUSIC first announced the album through Weverse on April 13, confirming the release date and describing the project as a record about change and growth that come from facing fear. 1
The rollout placed “BOOMPALA” at the center of the album campaign. The title was disclosed on May 6 through LE SSERAFIM’s official social channels and Weverse, with OSEN reporting that “PUREFLOW” is an anagram of “POWERFUL” and that “BOOMPALA” is a newly coined term created for this comeback. 2
“BOOMPALA” Release Rollout

The first major title-track preview arrived on May 8 at midnight KST, when the “Just BOOMPALA” video was released through the HYBE LABELS YouTube channel. ChosunBiz, citing OSEN, reported that the video opens with a conversation between Kim Chaewon and Huh Yunjin before introducing a portion of the “BOOMPALA” audio and the performance mood tied to the track. 3
A separate preview followed on May 18 at midnight KST through HYBE LABELS YouTube and LE SSERAFIM’s team social channels. Sports DongA reported that “BOOMPALA” samples Los Del Rio’s “Macarena” and frames fear as something that can become illusory depending on perspective and attitude, expressed through bright energy. 4
The promotional sequence continued on May 21 at midnight KST with the second music video teaser for “BOOMPALA,” released through HYBE LABELS YouTube and SOURCE MUSIC’s official social channels. ChosunBiz’s English report said the teaser included an arm-crossing movement derived from “Macarena,” further connecting the title track’s choreography with the sampled reference. 5
SOURCE MUSIC’s April notice summarized the album concept in direct terms. The company said, “LE SSERAFIM’s second studio album, ‘PUREFLOW’ pt.1, will be released on Friday, May 22,” and described the album as capturing “the changes and growth that come from acknowledging and confronting fears.” 1

Album Credits and Track Context
The album’s broader track information was disclosed through the “PUREFLOW” pt.1 highlight medley, posted on May 19 at midnight KST through HYBE LABELS YouTube and SOURCE MUSIC’s official social channels. The Fact reported that the album contains 11 songs, including “BOOMPALA,” and that Huh Yunjin participated in work on eight tracks. The same report also noted credit participation by Kim Chaewon, Hong Eunchae, and former members. 6
Within the available source material, “BOOMPALA” is described less as a standalone single and more as the focal point of the album’s comeback structure. Its title was revealed first, followed by a concept-related video, a preview emphasizing the “Macarena” sample, a highlight medley for the full album, and a second music video teaser focused on choreography.
The naming of “PUREFLOW” also supplies context for the album’s positioning. OSEN’s report, carried by Chosun, described “PUREFLOW” as an anagram of “POWERFUL,” while “BOOMPALA” was identified as a new word made for the comeback. 2 That wording aligns with SOURCE MUSIC’s stated theme of growth through acknowledging and confronting fears, though the available sources do not provide a full track-by-track explanation of the album concept.

With “PUREFLOW” pt.1 set for May 22, 2026, at 1 p.m. KST, LE SSERAFIM’s “BOOMPALA” entered release day with its title, sample reference, choreography cue, preview clips, and album placement already publicly established through official channels and entertainment reports.
