Handbill: "Ned Lagin, Phil Lesh and Friends -- A Concert of New Live Electronic Music -- *Seastones, Lilith and other works". For the asterisk on Seastones, there's a handwritten note that reads "This album has provided strong biophysical, electromagnetic, psychochemical reactions in both living & nonliving matter."
