HAYATO (piano) and HIRO (cajon) formed →Pia-no-jaC← in April 2005, and they specialize in instrumental music just as the duo's name suggests. The name is a combination of "piano" and "cajon", with the latter spelt backwards from the right. Self-taught musically, the simple unit of only keyboards and percussion has crisp and energetic sounds, blending oriental flavors with Japanese spirits. The word "hybrid" best describes their music. Needless to say their live shows are the most striking, where technique, sound and performance are all highlighted at once.
