Rearrange the letters of PUREFLOW and you get POWERFUL. According to The Korea Times, that anagram is deliberate. It's the kind of wordplay LE SSERAFIM's branding has used from the start; the group's own name is an anagram of "I'M FEARLESS." 'PUREFLOW' pt.1, the second studio album, came out on May 22, 2026, with BOOMPALA as the title track.
SOURCE MUSIC described the new chapter as a more internal look at growth, one born from confronting fear itself. Here's how the album was rolled out, what its eleven tracks are, and which official videos to open, from the pre-release single to the tour.
Where 'PUREFLOW' pt.1 fits
SOURCE MUSIC's discography lists 'PUREFLOW' pt.1 as the 2nd Studio Album. The first, UNFORGIVEN, came out in May 2023, so this is the group's first studio album in about three years. The official Japanese site dates the Korean release May 22, 2026. Official 'PUREFLOW' pt.1 page
The Korea Times reported that SOURCE MUSIC called the album a thematic evolution for the group. Its report gives the label's description: a more internal exploration of growth, born from confronting fear itself. The Korea Times on BOOMPALA, May 2026
The Korea Herald's report on the announcement, in April 2026, adds the label's contrast. According to SOURCE MUSIC, the group's earlier message was about strength through fearlessness; this album is about finding strength through understanding fear. The group announced the album on Weverse, and a logo motion video came first. The Herald reports that it unfolds in two phases: compressed inner energy, then that energy expanding outward to connect with the world. The Korea Herald on the album announcement, April 2026
That's worth putting next to the group's earlier albums. FEARLESS was about wanting to be the best. ANTIFRAGILE turned hardship into growth. UNFORGIVEN was about going your own way. This time, according to the label, the look turns inward, toward fear itself.
Start with BOOMPALA, the title track
The title track's name is another puzzle. The Korea Times reported that BOOMPALA is a coined word meant to pique curiosity around the world. SOURCE MUSIC called the mysterious title a deliberate move to spark intrigue about the song's sound.
The music video went up on HYBE LABELS on May 22, 2026, release day.
The video's credits list the choreography by Soyeon Park, Todd Williamson and JM Yrreverre. They also note that it contains choreography created by Mia Frye. An official Performance Film followed on May 25, with the same choreography credits.

CELEBRATION, the song that came first
Before BOOMPALA, the album was introduced with a pre-release single. CELEBRATION, track 3, had its music video on HYBE LABELS on April 24, 2026 (Korean time), four weeks before the album.

Watch the original on YouTube ↗According to the agency, as The Korea Herald reported, CELEBRATION captures a moment of self-realization and celebrates the inner strength the members gained through change.
The members wrote on it. The Korea Times reported that CELEBRATION carries songwriting credits from two members, KIM CHAEWON and HUH YUNJIN. The same report said the song had already made inroads on Billboard's charts.
Then came a short album teaser on LE SSERAFIM's channel on May 15, giving the release time as 1 p.m. KST on May 22. You'll find it in the table at the end.
Eleven tracks
The official track list runs:
1. Pureflow
2. BOOMPALA (title)
3. CELEBRATION
4. Creatures
5. iffy iffy
6. 우리 어떻게 더 사귈 수 있을까 (Need Your Company)
7. Sonder
8. Saki (feat. Aliyah's Interlude)
9. Irony
10. Trust Exercise
11. Liminal Space
The album opens with Pureflow, the title word as a song, before BOOMPALA. Track 6 is listed in Korean with an English title in brackets; the Japanese site lists it as Need Your Company.
SOURCE MUSIC's page doesn't describe the songs one by one, so we don't either. But the titles alone suggest a mood. Sonder, Trust Exercise and Liminal Space all sound like words for inner states. Do they fit the label's idea of looking inward at fear?

The PUREFLOW tour, and the charts
The album's name became the tour's name. LE SSERAFIM's channel posts its stage videos under 2026 LE SSERAFIM TOUR 'PUREFLOW'. The BOOMPALA stage from the Incheon shows went up on July 13, 2026.

The same report said BOOMPALA had passed 100 million Spotify streams, the group's 18th song to do so. At that point, the group was finishing a five-city European leg of the tour in Berlin.
