How we perceive music, whether it be as listeners, members of a crowd, a musician on stage, or anything in between, is always changing. Whether it is the sound from the instrument itself, the order in which the notes are played, or the real time persuasion of a raucous crowd, our perception is. Always. Changing. This month, we will listen to works rooted in free jazz and/or electronics by Ernesto Carcamo-Cavazos, Bernard Parmegiani, Roscoe Mitchell, and Encephalous.
