Invisible River was a collaboration with Alie Vidich in July, 2014. The performance used music from Mike Wall, Darren Morze, Jon Yerby, Barrios and Bach and lasted about two hours. From a lead boat with speakers, Mike and Jon headed down the Schuylkill River followed by hundreds of audience members in dragon boats and kayaks. Dancers used paddle boards, shore and island sites and where rigged to hang from the Strawberry Mansion Bridge.
