"The Chicago performances are billed as the final time the Dead's "core four" will perform together. Not only will the Chicago shows be webcast and simulcast in theaters, but Pay-Per-View broadcasts will be available from cable and satellite providers. Lesh, Kreutzmann, Hart, Weir, Hornsby, Chimenti and Anastasio will play two sets each night. A pre-sale for the webcasts is available here and costs $79.95 for all five nights. The pre-sale will run from May 1 to May 15."
