Green Day, Twenty One Pilots, Sublime

iHeartRadio‘s ALTer Ego festival will return to Los Angeles on Jan. 17, 2026, with performances from Green Day, Twenty One Pilots, and Cage the Elephant. The annual music event will be hosted at the Kia Forum and broadcast across the media conglomerate’s alternative and rock stations.

Sublime, Good Charlotte, Myles Smith, Gigi Perez, and Almost Monday will also take the stage at the event, performing songs that have become staples on alternative airplay, like Perez’s “Sailor Song” and Almost Monday’s “Can’t Slow Down.”

“If it were a lesser lineup you’d need a stronger host, but look at this list of performers – it’s incredible,” iHeartRadio ALT 98.7’s The Woody Show host Woody shared in a statement. “I can’t wait to see all these bands, and help guide a full house at the Forum through what’s going to be an insane experience!”

Lisa Worden, Program Director for ALT 98.7 and Senior Vice President of Rock and Alternative for iHeartMedia, added: “Sublime has had the No. 1 song at Alternative radio for the past four weeks eclipsing their previous No. 1 singles, Good Charlotte will play their first show in Los Angeles in over 10 years and Cage the Elephant is fresh off a U.S. tour with Oasis. All of these artists are ready to bring it! We cannot wait.”’

General sale for ALTer Ego 2026 will begin on Friday, Oct. 24 at 12 p.m. PST. Presale access will begin on Tuesday, Oct. 21, at 10 a.m. PST through Capital One, and ALT 98.7 will also host ticket giveaways.
