Bangkok’s Defying Decay has teamed up with Kellin Quinn For An Iconic Collab
The global metalcore scene is being brought to new heights with Bangkok’s alt-metal powerhouse, Defying Decay, officially releasing their new single “RX Regicide” through ONErpm. They’ve teamed up with the legendary Kellin Quinn of Sleeping With Sirens for a track that’s already turning heads across the alternative and post-hardcore world.
A Perfect Genre Mashup
“RX Regicide” is easily the band’s most polished and catchy release to date. It’s a smart play too. The track is specifically designed to bridge that gap between heavy metalcore and melodic alt-rock. You get the best of both worlds here: frontman Jay P. Euarchukiati brings an aggressive, gritty energy that fans have loved since the band started in 2010.
At the same time, Kellin Quinn adds his signature melodies that have made him a staple in the scene. The song feels like it was tailor-made for high-energy streaming playlists.

Taking Bangkok Global
Defying Decay might be based in Thailand, but they’ve spent the last decade proving they belong on the world stage. They’ve already toured with heavyweights like Ice Nine Kills, Trivium, and Atreyu, and this new release is part of a massive push into the UK and European markets. With a multi-page spread coming in Metal Hammer and features lined up in Kerrang! and Rock Hard Italy, it’s clear the industry is starting to pay serious attention to what’s coming out of Bangkok.
Crossing Borders
The collaboration, which is distributed by ONErpm, is a genius move for both artists. While Defying Decay is already a force in Thailand and Germany, Kellin Quinn’s massive reach in territories like the Philippines and Australia where he has over 590,000 monthly listeners gives this track a huge international platform. “RX Regicide” is the lead single for their upcoming album Synthetic Sympathy, and if this track is any indication, everyone is in for something pretty explosive.
If you’re into music that’s dark, high-energy, and a little bit dramatic, you’ll definitely want to keep this one on repeat.
