Alki BeachRock Concert
On 10 August 1969, a permitted rock concert at Alki Beach in West Seattle escalated into disorder involving police, concertgoers, tear gas, a reported firebombed police car, arrests and disputed injury reports. The incident is also linked in later accounts to the University District unrest that followed the next night.
Core Record
What Happened
Reviewed sources describe the event as a free outdoor concert at Alki Beach. HistoryLink reports that Seattle police fired tear gas after a police car was firebombed and that six arrests followed.
The same core account says tear gas drifted into nearby homes and a grocery store, affecting residents, including an infant child. That detail matters because the impact was not limited to people inside the concert crowd.
Later sources connect the Alki Beach confrontation to unrest in Seattle’s University District on 11 August 1969. That makes the incident part of a wider city disorder sequence, not just a beach gig gone sour.
Injury reporting is weak. One AP snippet says police and civilians were injured, but the accessible material does not provide a clear count. No fatality directly tied to the Alki Beach concert was verified in the reviewed sources.

Conflicting Information
Disputed Detail
Cause and responsibility
Sources agree that a police vehicle firebombing was reported and that tear gas was used, but they frame the escalation differently.
HistoryLink
Says a person allegedly firebombed an unattended police car and police then responded with riot gear and CS gas.
The Seattle Star
States the concert was officially permitted and frames the police action as abrupt and severe, with officers allegedly harassing attendees before escalation.
Editorial note: this is less a disagreement over whether disorder occurred, and more a dispute over who drove the escalation. Classic 1969: everyone brought a source and nobody brought a tidy answer.
Disputed Detail
Injury reporting
The reviewed material supports that injuries were reported, but it does not support a firm injury count for the Alki Beach incident.
