The original idea behind Zalo was to challenge conceptions about how a duo is supposed to sound and what kind of music they should play.
The music tries to be original and unique; on stage it's always performed 100% live. Hanna sings, plays harmonica, some keyboard and also makes percussive beats with her voice. J.J. uses different kind of acoustic guitars combining acoustic sound with electric one. He also plays basic keyboard without sequencer and electronic drum pads with samples made by Zalo.
