Green Day and Cage The Elephant will headline iHeartRadio’s ALTer EGO 2026 concert event in January at Kia Forum in Los Angeles. The lineup features twenty bands scheduled to perform throughout the day.

The festival returns for its twelfth year with additional acts including The Offspring, Glass Animals, and St. Vincent. Tickets go on sale Friday through Ticketmaster, with prices starting at $69 before fees.

Green Day continues touring behind their latest album “Saviors,” which debuted at number four on the Billboard 200 chart earlier this year. The band recently completed a stadium tour across North America and Europe.

Cage The Elephant will perform songs from their catalog including tracks from “Neon Pill,” released in May. The Kentucky-based band earned their second Grammy Award for Best Rock Album with their previous release “Social Cues.”

iHeartRadio expanded the festival format this year to include performances across two stages instead of one. The event runs from noon to 11 PM on January 11, 2026.

Pre-sale access begins Wednesday for iHeartRadio listeners who register through the company’s app. Kia Forum capacity for the event is set at 17,500.

The Offspring, Glass Animals, St. Vincent, Phantogram, Milky Chance, and Cavetown complete the main stage lineup. Second stage acts include Destroy Boys, Militarie Gun, and Ultra Q among others.
