Aerosmith has announced a historic two-night concert at the Hollywood Bowl in Los Angeles, California, on October 29 and November 1, 2026. The event, titled California, Dream On: Aerosmith & Friends, will celebrate the band’s enduring legacy and influence in rock music. Guns N’ Roses will join as very special guest performers for both shows, marking a rare collaboration between two of the most iconic rock bands in history.

The concert will feature an electrifying lineup of artists spanning rock, country, hip-hop, and alternative music, including The Black Crowes, RUN DMC, Heart, Billy Idol, Chad Smith, Duff McKagan, Jerry Cantrell, Marcus King, Mike Inez, Nuno Bettencourt, Pat Monahan, Sammy Hagar, Steve Stevens, Sully Erna, Tom Morello, Adam Wakeman, Audley Freed, and Kenny Aronoff. Don Was will serve as music director. Final nightly lineups will be announced at or near showtime and are subject to change.

In addition to the main performances, the event will include a variety of VIP upgrades such as access to a pre-show lounge, limited edition jackets, and exclusive T-shirts. Ticket information is available at aerosmithandfriends.com.

The announcement follows a recent update from Slash, who confirmed that Guns N’ Roses will perform both nights. While the full setlist has not been released, Slash indicated that the set will include a mix of Aerosmith and Guns N’ Roses songs, with a selection of tracks to be determined. The band’s upcoming album, Flying Blind, will be released on February 26, 2026, following pre-production work completed in early 2025 and recording sessions in Florida.
