Parade sound system

Phin Prayuk Style

Phin prayuk is the music of ordination and wedding processions, where a band and a vehicle loaded with speakers parade through town. It is not music to hear on a stage, but music that moves down the street and pulls people in.

Phin Prayuk Style is a system for bringing that format as it is. A 220V sound system, the same voltage as in Thailand, rides on a cart imported from Thailand, and we parade while it plays from a generator.
