Summer is the time of of love, music and a little bit of adventure.

Nothing captures this more than the craziness of a music festival, and the Woodstock Music Festival of 1969 set the standard for every Bonnaroo, Lollapalooza, Coachella and music fest that has happened since.

On Aug. 15, 1969, 400,000 concert-goers descended on an ad-hoc concert stage that was built days prior when the venue unexpectedly changed from Mills Industrial Farm in Walkill, N.Y., to Yasgur Farm in Bethel Woods, N.Y.

They came to see to bands such as Santana, The Grateful Dead, Creedence Clearwater Revival, The Who and Jimi Hendrix, jamming to the music in muddy fields and jamming up traffic for miles around.

Below are some of the characters that came to rock, and who lived the legacy that lasted far longer than three days of peace, love and music.

The "Free Stage" essentially functioned as both a place for the scheduled performers to jam and as an open mic stage for festival goers. (Ralph Ackerman/Getty Images)
