MARK Harmony - the Band

​

MARK Harmony is a Marshallese band composed of Matthew John, Arsi Lokot, Raygon Jacklick, and Kairo Langrus. The name "MARK" is an acronym representing the first letter of each member's name. The group began as a five-member ensemble but has since evolved into the four-member band it is today.

​

The band made their debut performance in 2017, singing "One More Time" by the Katinas at their high school in Springdale, Arkansas. In 2018, they performed an original song titled "Whoa" at the Arkansas All-Choir Convention, marking the start of their musical journey.

The band's interest in the Marshall Islands' nuclear-testing legacy led them to arrange a meeting with the Marshallese Educational Initiative. During this meeting, they spoke with Benetick Kabua Maddison, who leads MEI's nuclear legacy programming and serves as the organization's executive director. After an informative session on this topic, the band composed a song dedicated to the nuclear legacy of their homeland—a place none of them had visited before but about which they had heard many stories from relatives and seen images online. Their song, titled "Oh Sweet Marshall Islands," has been performed at local and international events hosted by MEI to commemorate and educate others about this tragic chapter in the islands' history.

​

MARK Harmony has performed at several significant events, including an international climate conference in Antigua and Barbuda, a private event hosted by Marshall Islands President Hilda Heine, a nuclear award ceremony recognizing MEI attended by United Nations officials, and an interview with The New York Times that captured the attention of millions across the United States.

Marcina Langrine manages the band and also serves as MEI's Operations Coordinator. She has played a crucial role in connecting the artists with numerous opportunities.

​

MEI and MARK Harmony exemplify a community-driven collaboration where cultural artistry and advocacy intersect. MEI provides the structural and ideological framework for preserving Marshallese heritage and addressing historical injustices, and MARK Harmony contributes musical talent and youth appeal to make these efforts resonate and captivate audiences. Together, they sustain Marshallese culture and ensure that its stories and struggles are heard on both local and global stages, with MEI serving as the band's label.

MARK Harmony creates music that spans diverse genres, blending island reggae, country, soul, and R&B, with harmony as a central theme. With their new album, the band aims to continue producing music that highlights issues affecting the Marshall Islands and connects with the global community, while also incorporating messages about the climate crisis, international solidarity, peace, and hope.

The Album

 

"Nuclear Free World" was produced with support from the Marshallese Educational Initiative, Executive Producer Benetick Kabua Maddison, Music Producer Jared Jamieson, Co-Producers Blaise Dupuy and Dr. Kathleen Sullivan, and Master Engineer Dennis Mitchell at Stonebrown Studios in Brooklyn, New York. Marcina Langrine kept the band focused throughout production. Marino Morris, MEI's artist-in-residence and Media Coordinator, created the cover art, which depicts the band standing on the Runit Dome with the blood-red Castle Bravo mushroom cloud in front of them, overlooking a once-pristine, nuclear-free paradise.

​

Production began in November 2024 and was completed in June 2026, just before the Solidarity Concert on June 30, which marked the 80th anniversary of Operation Crossroads—the first of 67 U.S. nuclear weapons tests conducted in the Marshall Islands. Each track on the album addresses aspects of the nuclear legacy: the tests, displacement, health effects, the fight for justice, and the hope for a nuclear-free world. The music is dedicated to the Marshallese people, nuclear frontline communities, activists, and anyone committed to protecting the planet, their loved ones, animals, and all that is threatened by nuclear harm.​
