| Paul van Emmerik gives the following details on this work: "In Solo 58 from Songbooks, Postcard from Heaven and
Two6 Cage distributed the available ranges in a number of partial ranges and selected by chance a limited number of tones, taken
from these partial ranges." In Postcard from Heaven "five different combinations of pedalpositions were independently composed for
every subset". Sources: Paul van Emmerik: Thema's en Variaties; David Revill: The Roaring Silence; New York Public Library online catalog |
