HiJinx Festival Returning to Philly With GRiZ, Knock2 and More in 2025

The City of Brotherly Love will also see a massive b2b set from ILLENIUM and SLANDER, among other elite DJs.

Philly has never been shy about celebrating the end of the year (or Eagles victories) but few parties pack as much wattage as HiJinx. The two-day EDM festival is set to return to the Pennsylvania Convention Center December 27th and 28th, promising enough bass to rattle the Liberty Bell all over again.

As 2025 gives way to 2026, HiJinx looks primed to keep Philly dancing long past midnight with its kaleidoscopic light shows, towering stage designs and massive lineup. For locals, the festival offers a festive alternative to cheesesteak debates and post-holiday hibernation. For visitors, it’s a chance to see the City of Brotherly Love transform into a thrilling rave setting.

This year’s headliners are GRiZ, Gryffin, ILLENIUM b2b SLANDER, Seven Lions and EDM.com Class of 2023 artist Knock2. Attendees will also take in a ruthless performance by Skull Machine, the collaborative duo of dubstep and bass music stars Black Tiger Sex Machine and Kai Wachi. The undercard is no less impressive, featuring performances by Daily Bread, Hamdi, Kaleena Zanders and Zingara, among others.
