Heiakim, Arash Buana, and Hnata Release Their First Collaboration ‘Underwear’

Indonesian musicians Heiakim, Arash Buana, and HNATA are releasing their first-ever collaboration ‘underwear’ that came around through simply hanging out together and taking turns on the microphone. 

Although they have been friends for a long time, this marks the first time the three artists have made a song together. Written spontaneously in a single session, the track captures their thoughts and energy in real time as each artist took their turn to apply their personal artistic touch to the project. 

Blending alt-pop rock with a hint of indie pop, the song features warm, band-driven production with laid-back, conversational vocals and subtle rap influences. Beneath its laid-back sound, the song explores themes of overthinking, emotional distance, and quiet burnout, capturing the feeling of moving through life on autopilot and the idea of feeling “just ok”. 

This collaboration highlights the trio’s natural chemistry, combining each of their individual styles into something that feels effortless and cohesive. Rather than sounding overproduced or overthought, the song relies on spontaneity — allowing each artist’s individuality to shine while creating an atmosphere that feels intimate, honest, and genuine.

The single will be available on all digital streaming platforms starting May 22, 2026.
