Material Evidence

November, 2017

Material Evidence was written in 2017, and is the first large ensemble work of Landon’s to incorporate his ideas on “behavior in music”. Work began by slowing recorded performances to approximately one-tenth normal playback speed and analyzing how each instrument behaved, at the micro level, as they were played using a variety of techniques. This behavior acted as a model for composition, and each instrument was assigned behavioral characteristics, both as individuals and as those interacting with other instruments. Energy and intensity, as they relate to gesture, is especially audible, and often provides structural landmarks within the overall formal structure. The piece is highly textural, and the electronic part embodies all of the behavioral characteristics of the ensemble. The line between what is coming from the ensemble and speakers is often blurred. Try to determine who is “doing” what!
