The artists' work was presented side-by-side in two mid-September concerts last year, highlighting Penderecki's influence on younger composers, at the European Congress of Culture in Wroclaw. The composers went to Krak w's studio immediately after the performances to oversee the recording of the same music, along with one other piece by Greenwood.The Wroclaw concert included two works by Penderecki dating from the early 1960s: Threnody for the victims of Hiroshima and Polymorphia (for 48 strings), the latter of which inspired the Greenwood piece on the program, 48 Responses to Polymorphia; all three are on the record.
