If the expression‘, one man band’, often recalled a shabby tone-deaf street artist with a drum on their back and cymbals attached to their knees, it now refers to musicians who create the most diverse and dynamic music. This documentary follows a‘one’man or woman band who works in Europe and US. Such artists who worked on films including Man From Uranus, Ninki V and Honkeyfinger have every reason to be this ‘one man in the band’as it may be that they cannot find a drummer, or they simply want to create more raw and vibrant tunes. Whatever the case is, the common ground is they have a passion in music that enables them to stand on their own. Their music achievements also shine through the inventions of innovative musical instruments from Theremin Rock, a musical instrument born in the 1920’s USSR, Hornicator, an instrument made of parts from a phonograph to an accompaniment instrument made from bicycle tires, there are quite a number of instruments that create unique sounds. Perhaps the‘one man band’is a musical expression that truly represents a modern society becoming more and more individualized. (Chun Jin-su)
