The details, in daylight
Dead Kennedys played The Observatory in Santa Ana on 9 September 2026, with Flipper in support. This show has already taken place — see Dead Kennedys's page on KeenToGo for their upcoming dates.
The Observatory is a Live Nation concert venue at 3503 S. Harbor Blvd. in Santa Ana, CA. It is three rooms rather than one: the main Observatory room, the smaller Constellation Room, and the open-air Observatory Festival Grounds, and the venue lists each show under the room it plays. Dead Kennedys is a rock act.
