As of right now, Bisco will need to find a new home. Live Nation and the county are at odds in regards to the contract of the amphitheater.
Negotiations are happening, but from what I hear, the county is upset with the festivals, lack of parking, and complaints about people parking on private property. The current contract is up on 9/1, so they need to start making some moves to get it done.
The county will be hue idiots if they allow LN to walk. There is no other management and booking company that would take on operating the amphitheater. It would just sit there rotting.
As for LN, they are partners with The Biscuits and The Allman Brothers, so both Peach and Bisco could go on somewhere in Eastern, PA as all booking for both shows is done out of the Philly office.
