Here, Skrillex teams up with British producer Fred Again and British grime MC Flowdan for a thunderous, bass-forward banger. The song features additional uncredited vocals from American singer Elley Duhé and Jamaican-American singer-rapper Beam.
During Flowdan's ominous flow, he references the smell of spiffs, which is so strong you can hear it. But when he steps into the "jungle" (room) he makes a noise so loud it overshadows the aroma.
The word "rumble" has several meanings. Here, it refers to the sound of a large crowd, which Flowdan describes as "killers in the jungle."
"Rumble" was initially a collaboration between Fred Again and Flowdan that took place in 2018. After Skrillex met Fred and heard the song for the first time, he asked for the track's stems and created his own version. "I didn't like it," he told Jack Saunders on BBC Radio 1, "I thought I ruined the song. I was scared to play it."
Eventually, the three of them started working on "Rumble" again in the first half of 2022.
English producer Four Tet was also involved in the song's production before getting "kicked off" from the project. "Four Tet is an honorary producer on everything we do, pretty much like a ghost producer," explained Skrillex.
"Rumble" first saw the light of day when Fred Again included it in his June 29, 2022 Boiler Room session broadcast from London. The song became a fan-favorite from the set, generating anticipation for its official release. This led to unofficial versions of the song appearing on YouTube, before Skrillex released it as a single through Atlantic Records and Owsla on January 4, 2023. It is the lead single from Skrillex's double album QFF / DGTC.
