Landmine – Disklavier / sound-processing

landmine (2000 rev. 2007/2017) is a composition and performance project created for pianist Kathleen Supové,, on Yamaha Disklavier Grand Piano and with live-audio processing by Dafna Naphtali.  Commissioned in 1999 by American Composers Forum for Supové, it premiered that year.  The various sections of the piece are named for Unix processes, each one related to the musical concepts for that section. The piece has been performed in NY, Florida and Australia, was finally recorded by Supové and Naphtali in 2017, and performed most recently in 2019 at Areté in Brooklyn, NY. in 2019, landmine was finally released on Supové’s critically acclaimed album “Eye to Ivory” (Starkland label).

The composition and performance of this piece rely heavily on programs Naphtali has written in Max/MSP:  The piano part is based on a real-time algorithmic compositional “toy” that she developed, inspired by the music of Nancarrow and Xenakis.  It was used to generate all the basic harmonic and rhythmic materials used in writing the piece. 

The live audio processing in the piece uses a program she’s been developing since 1993 to control an Eventide effects processor, and it is an extension of the computer-instrument she uses in composed and improvised performances. Finally, in two sections (most notably the last measures of :q! quit without saving), the pianist improvises with and against the same algorithm that was used to generate the raw material for the piano parts, as well as with a program that creates “piano for 14 hands”.  The title reflects the way the “toy” algorithm behaves — inserting chords and repetitions in unexpected places that could potentially overwhelm the performer.

A standalone installation version of Landmine 1999/2007/2019 using an algorithm in Max to control the Disklavier and and create the piano parts for the composition. The piano reacts to anyone who wishes to play along. This was recorded at Extended Piano Festival in NY 2011 (works for Disklavier)
