The original Woodstock in 1969 had one stage with a rotating disc to help keep each act on schedule. Of course, that didn't happen.
Woodstock '94and'99had multiple stages -- as will Woodstock 50, which will be held August 16th to the August 18th in Watkins Glen, New York.
The performances will run for 13 hours a day over four stages, with a midnight curfew on Friday and Sunday, and a 1 a.m. cutoff on Saturday.
Three-day passes go on sale April 22nd, at which point additional acts will be announced. Ticket prices have not been revealed, and there will be no single-day passes.
Among the headliners are Robert Plant,Santana,John Fogerty,Dead and Company,The Killers,Imagine Dragons,David Crosby,Jay-Z,Greta Van Fleet, Miley Cyrus,Chance the Rapper and Brandi Carlile. The Black Keys are no longer on the bill because of a scheduling conflict.
