Fans gathered on Thursday (August 15) to mark 50 years since the Woodstock Music & Art Festival.
The 1969 extravaganza, which happened on a dairy farm in Bethel, New York, became one of the most significant counter-culture events in history.
Acts such as Jimi Hendrix, Janis Joplin, Joan Baez and the Grateful Dead all played, paving the way for the modern music festival as we know it today.
More than 400,000 people turned up; organisers were expecting just 50,000.
Michael Lang, co-creator of the original festival, attempted to organise a commemorative concert for the anniversary. The event was cancelled after organisers lost headliners including Miley Cyrus, Jay-Z and some performers from the 1969 event.
The commemorations were run by the Bethel Woods Centre for the Arts. There were fireworks, food, and, of course, music. The centre is largely focused on exhibiting pop culture from the US in the sixties and is located on the site of the original festival.
