SOUND CHECK: Pandemonium: Share the stage

IT'S NOT OFTEN that the lines between audience and performer are blurred. But at Concrete Pandemonium, the world is a stage for those who care to share their music, poetry, political rants or anything else that might be on their minds.

The brainchild of Leah and Chloe Smith, the local sister duo at the core of folk music collective Rising Appalachia, Concrete Pandemonium is a communal event that includes visual and performance art as a means to spread one's messages and emotions.

And with the third edition of this event taking place this weekend, attendees can expect to be dazzled by the likes of Good 'N Plenty Burlesque, hip-hop choreography, fashion shows and percussive performances by acts such as Earthshaking Samba and Rising Appalachia, the headlining band.

But those not on the bill who want to do more than observe can also take part in the festivities. Costumes are encouraged.

Care to share a random thought or piece of poetry? Want to start a drum circle or strum a few chords? Have some activist leaflets you want to distribute?

Concrete Pandemonium offers a receptive audience for all that and more. If you don't care to participate, the nighttime fire dances, theatrical performances and positive vibes will keep you just as entertained.
