Once Upon A Group by Ben Azarm

In the 1963 ONCE Festival, a piece by Ramon Sender called Information was introduced. The score came on a huge roll of plastic transparent material and was set into motion by a number of people unrolling the score for the instrumentalists to follow, while at the same time another player improvised a great deal of informative material. Bob Ashley delivered the message by talking at length about the performance going on next to him. p.1
