Playa Info (at Center Camp) is looking to fill their stage and trying to get the word out, so I think it might also be okay to tell you:
Looking for an intimate venue? For acoustic / spoken word / low amplified DIY performances,we've got a stage and cool setting that's just right day or night. Come check 'em out! Performers step right up or sign-up on the schedule at the stage.
