CO is like ... well ... to describe the band is rather hard since there is no defined sound and what they have put out defines any genre
the best you can describe the music as is "Experimental sound based electronic music"
Early Contagious Orgasm was more industrial/noise based with focus on repetitive loops and sampling
very gritty
then as the years went on He/they became more experimental and centered around dadaism/avant garde soundscapes
basically this band is one of the coolest and most underrated of the Japanese noise and experimental music acts out there they hardly get any attention and you'd be hard pressed to hear of them anywhere so enjoy this exposure to what might become one of your next favorites
