Signal Bell, a senior recital by Ueaangkun Nurak (hornist) will perform solo and chamber music pieces using a concept to represent the idea of 'signal' and 'bell' to reconcile a sound (music) with human civilization from the ancient past through music composed by Mozart, Strauss, Persichetti, Bartók and Bozza. For the creative work in this recital, the performer had experience in a research field trip as a training ethnomusicologist to explore the bell’s sounds in Pang Ma Pha, Muang, Khun Yuam, and Mae Sariang districts at Mae Hong Son province which is a natural heritage area in Northern part of Thailand last November 2021, those bell's sounds inspired the performer to create a musical collage with the VDO. The performer hopes that the audience can approach those sounds and invite them to open their minds in the culture's imagination.
