See Knocked Loose and Poppy bring total carnage to late-night TV with their performance of the GRAMMY-nominated Suffocate.

Louisville metallic hardcore insurgents Knocked Loose are living out a truly insane existence. Knocked Loose have been a big band in the heavy-music world since the pre-pandemic days, and they continue to get bigger even as their music gets more and more intense and abrasive.

“Suffocate” has been a standout track ever since Knocked Loose revealed the song earlier this year, but the cut is only picking up steam. As previously reported, “Suffocate” has been nominated for Best Metal Peformance at the 2025 Grammy Awards, running against the likes of Metallica, Judas Priest, Spiritbox and Gojira.

Punk bands are rarely invited to play on late-night TV shows, let alone metal and hardcore bands, so it was something special to see Knocked Loose on Tuesday’s episode of Jimmy Kimmel Live!.
