Gruesome Singaporean grinders WORMROT were scheduled to play in Somerville last September, but a holdup at U.S. Customs left local fans disgruntled. Luckily, the band are honoring their commitment and making their Boston debut at O’Brien’s Pub this Saturday in Allston.

Stylistically, Wormrot resemble Nasum and Phobia -– on their new LP, the group couples discordant blasting with crusty grooves, deftly avoiding the sterility of some modern grindcore acts and the sloppiness of others.
