A multimedia museum, marking the sex, drugs, rock music and politics of the historic 1969 Woodstock festival has opened in the United States.
That year, half a million hippies turned out in the small farming village of Woodstock, north of New York City, to enjoy music performances by the likes of Jimi Hendrix and Janis Joplin.
The Museum at Bethel Woods is a country drive from the former farm at Woodstock.
The 240-hectare farm is home to the 104 million dollar arts and performance centre, with around one thousand square metres of exhibits, including photos of concert-goers swimming naked or praying for rain to stop.
The concert came together once legendary guitarist Jimi Hendrix agreed to perform.
"Once Jimi Hendrix said yes, we had the floodgates open," organisers say in a video museum-goers see at the new blast-from-the-past facility.
The documentary also screens the turbulent events of the times, includes assassinations of political icons John F Kennedy, Robert F Kennedy, and Martin Luther King Jr.
