Japan's SiM Unleashes Heaviest Reggae Punk Single Yet, World Tour Teased

The four-piece that wrote the Billboard No. 1 "The Rumbling" for Attack on Titan didn't soften their follow-up. SiM (Silence iz Mine), the self-described Reggae PUNX from Shonan, Kanagawa, released "FiVE TiMES DEAD (by my wallet)" on April 1 via UNFD, declaring in their own words: "SiM's heaviest, most chaotic reggae punk track yet. World tour soon." Those last two words are the ones to watch.

The timing was anything but accidental. The single landed three days before SiM hosted their annual DEAD POP FESTiVAL in Kawasaki (April 4-5), a sold-out two-day event drawing 15,000 people per day. The bill reads like a primer on Japan's hybrid-genre underground: BABYMETAL, MAXIMUM THE HORMONE, coldrain, Crystal Lake, MAN WITH A MISSION, and Australia's THORNHILL across both days, with SiM performing as organizers and headliners on each night. "FiVE TiMES DEAD" will land near the peak of each set, a mosh-pit detonator for a crowd fluent in every SiM riff. The likely companion pieces: "The Rumbling," still the band's biggest international statement, and "UNDER THE TREE," their 2023 Attack on Titan Part 3 contribution, which shows the slower, more melodic edge of the same hybrid architecture.

For reggae listeners who haven't yet crossed into SiM's orbit, the entry point is the rhythm section. The band has spent over two decades threading reggae's offbeat pulse and dub-derived low-end weight through metalcore and nu-metal frameworks. Six full-length albums and a live resume spanning Rock Am Ring, Download Festival, Graspop, Louder Than Life, and Welcome To Rockville confirm they are not a novelty act. "The Rumbling" alone passed 200 million streams and reached No. 1 on Billboard's Hot Hard Rock Songs, proof that the hybrid formula travels.

If 311's reggae-rock lockdown, Skindred's ragga-metal ferocity, Sublime's punk-dub instincts, or Rancid's ska-informed aggression already hold space in your rotation, SiM slots in at the harder, faster end of that same spectrum without abandoning the groove.

A practical listen-before-you-go sequence: open with "FiVE TiMES DEAD (by my wallet)" on YouTube where the music video is already live, then move to "The Rumbling" for the commercial peak, then close with "UNDER THE TREE" for the melodic tension that rounds out the picture. Those three tracks map the range a DEAD POP crowd hears across two nights, and sketch exactly what a world tour set list will likely look like.

A seventh full-length studio album is also in progress, with SiM reportedly planning a domestic experiment tour later in 2026 to road-test new material ahead of its release.
