South Korean boy group SEVENTEEN commemorated their 10th anniversary with the explosive release of their new music video "THUNDER" on May 26, 2025. This track is the lead single from their fifth full-length album, HAPPY BURSTDAY, which features a total of 16 tracks including 13 solo songs, one from each member, marking a first in the group's discography.

The release was preceded by a high-energy teaser and a special live performance held at the Jamsu Bridge over the Han River, where SEVENTEEN became the first K-pop act to perform. The group delivered a dynamic hip-hop dance performance of "THUNDER" alongside fan favorites such as "Hot," "Rock with You," and "Very Nice." The bridge’s fountains were synchronized with the music, creating a spectacular visual experience for fans attending the "B-Day Party: Burst Stage" event.

Produced by Han Sungsoo and directed by Samson, the "THUNDER" music video showcases SEVENTEEN’s signature energy and artistic growth through powerful visuals and an EDM-based dance-pop sound with explosive hooks. The concept centers on themes of self-reinvention and courage, symbolized by the group's arrival at the fictional "Blitz Club," a metaphorical space for transformation and rebirth.

Fans worldwide have enthusiastically embraced the release, actively streaming and sharing the single, with the group aiming to achieve 15 million views and 1 million likes within the first 24 hours. The global fanbase, known as Carats, has been instrumental in amplifying the celebration through creative engagement and support.

The album HAPPY BURSTDAY was officially released on May 26 at 6 p.m. KST, cementing SEVENTEEN’s continued evolution and commitment to pushing musical boundaries as they celebrate a decade of success in the industry.
