Helmut Lachenmann (born 1935) premiered Echo Andante, his second piano work, at the Internationale Ferienkurse für Neue Musik (Darmstadt, Germany).

The work abounds in ingenious effects for creating an “aura” — keys pressed down silently, recaptured after attacks, sounds filtered through pedal changes…

Echo Andante is played with this in mind by Andrew Infanti (live performance).
