Feldman's long lost piece for solo electric guitar has been reconstructed thanks to the triumvirate effort of guitarist Seth Josel, Feldman archivist Chris Villars, and Other Minds. Unknowingly stolen in 1967 along with Christian Wolff's guitar case, the piece has remained shrouded in mystery for decades. The score is reconstructed in two versions: one based on a single page sketch by Feldman titled "The Possibility" and another based on a recording of Wolff performing the work as part of a concert presented in 1966 at San Francisco's Tape Music Center formerly located at 321 Divisadero Street from the KPFA archives and in the possession of Other Minds. Following Feldman archivist Chris Vallars' discovery that the tape existed, he contacted Other Minds initiating what would become the reconstructed piece. The publication by Peters Edition includes both versions and essays by Villars and Josel.
