Diamond-shaped isle between Malaysia and Indonesia, Singapore stacks 6 million inhabitants onto roughly 284 square miles of one of the most densely populated spots on the planet. That’s about half the size of the smallest state in our union (Rhode Island). Wormrot commandant Arif Suhaimi can incite every last one of them into the mosh. Alongside axe maniac Rasyid Juraimi since 2007 and early days drummer Fitri, back following a nine-year stint by replacement Vijesh Ghariwala, the grindcore trio erupts like a volcano across four LPs. Suhaimi departed after pandemic surprise Hiss, then returned last year to touch off more human tsunamis, including this month’s “Outburst of Annoyance” live single for audio extremists Earache. No/Mås and Bosh support. – Raoul Hernandez
