Work Overview

Vinyl is such a great physical representation of music; it's big, bold, and tactile. Putting on a record is an event one that makes the listening experience more enjoyable (not to mention the great audio quality of vinyl records!) Agerasia uses altered or "ruined" vinyl as a major sound source in combination with acoustic instruments. The piece takes some inspiration from Ligeti's Cello Concerto [1966] in that the cello and bass clarinet often play very sustained static tones. I felt it necessary that the acoustic instruments play a more sustained role as the vinyl recordings contain large amounts of variation, (the variation coming not only from the recorded material itself, but from the "prepared" nature of the vinyl). Sustained tones often fade from cello to bass clarinet and meandering melody fragments in the cello are offset by stuttering passages from the bass clarinet. All of this inscribed on a cosmic background of static noise, skipping fragments of 80s pop music and percussive clicks and pops by way of the three vinyl records. The vinyl recordings used in Agerasia contain three sections, each with a different ruining.
