The Mountain Pass — A Song Inspired by BTS's Return

The Return: On March 20, 2026, K-pop supergroup BTS released their highly anticipated album Arirang, marking the first project featuring all seven members in nearly four years. The group had been on hiatus since 2022 as each member completed South Korea's mandatory military service.

BTS — consisting of RM, Jin, J-Hope, Jimin, V, Suga, and Jung Kook — is the most successful K-pop export of its generation, having sold more than 500 million units and breached over 104 billion streams worldwide. Before their hiatus, they became the first Korean group to top the US Billboard 200 album chart and Billboard 100 singles chart — six times each. They're one of the all-time best-selling groups of any genre, from any nation.

In South Korea, all able-bodied men between ages 18 and 28 must serve 18 to 21 months in the military. There was debate about whether BTS, practically national treasures, would earn special exemptions given to some athletes and classical musicians. They didn't. Jin, the oldest member, enlisted first in December 2022 and was discharged in June 2024. The others followed in staggered waves, with Suga completing his service last in June 2025. For nearly four years, the Army — BTS's devoted fanbase — waited.

The new album, named after "Arirang," a centuries-old Korean folk song about parting and longing, explores themes of connection, distance, and reunion. USA Today described it as the group's "most experimental project to date," infusing hip-hop with traditional Korean folk music. On March 21, BTS performed their first live show in years at Seoul's Gwanghwamun Square before 250,000 fans, streamed live on Netflix. Presales for the album reportedly surpassed 4 million copies within one week of announcement.

But here's what struck us: they didn't return to the world they left. K-pop exploded during their absence. Groups like NewJeans and the artists behind Netflix's KPop Demon Hunters brought unprecedented mainstream success, including the genre's first Grammy win. Billboard journalist Tetris Kelly told NPR: "A lot of people are crediting ['Golden' and KPop Demon Hunters] with bringing people into K-pop. But I don't think that the success of even 'Golden' would've happened if BTS didn't already push that door open."

Why We Made This Song: When we saw this story, we didn't see K-pop. We saw something universal: coming home after years away to find everything both familiar and changed. The chair you sat in worn by someone else. The garden speaking a different language. Children who grew without you watching. This isn't just about seven musicians returning from service — it's about anyone who's ever left for war, college, divorce, or time itself, and returned to a place that moved on without them.

We wrote "The Mountain Pass" as atmospheric post-rock with shoegaze textures because that sound IS returning home in slow motion. Sparse fingerpicked arpeggios in the verses — tentative, uncertain, like standing outside a door you haven't opened in years. Building through layered reverb-drenched guitars to sweeping crescendos in the choruses — the overwhelming flood of memory and change colliding. The bowed cymbals add an ethereal, ghostlike quality. It's the sound of remembering while standing in the present.

The title comes from "Arirang" itself — literally "mountain pass" in Korean, a metaphor for parting and reunion, for the journey between who you were and who you've become. In our song, the mountain pass isn't a place. It's the gap between then and now, the space you cross to come home.
