In 2004, Levine conducted his last concert for Pope John Paul II, leading the Pittsburgh Symphony Orchestra and members of the Mendelssohn Choir of Pittsburgh, the London Philharmonic Choir, the Kraków Philharmonic Choir, and the Ankara Polyphonic Choir in the "Papal Concert of Reconciliation." This event was the first time that any American orchestra had performed for any Pope in the Vatican. The concert, broadcast worldwide, included Gustav Mahler's Symphony No. 2 "Resurrection", and "Abraham", a specially-commissioned motet by John Harbison.
