Cobra is an improvised game piece created by John Zorn for any number of musicians. It's controlled with a set of instruction cards that are held by the conductor, but anyone taking part can call for a specific instruction. On Sunday it was played by a group of musicians from the Noise Upstairs jam night(including me)and conducted by Rodrigo Constanzo, although it can only really be Cobra if John Zorn himself does it.
