Members: H ZETT M (Masayuki Hiizumi), Piano H ZETT NIRE (Masahiro Nirehara), Double bass H ZETT KOU (Kou), Drums The band leader H ZETT M's colorful career has progressed from chart-topping Ringo Sheena's projects to "Samurai Jazz Band" PE'Z, a slew of more or less off-kilter solo releases, collaborative anime covers, vocaloid music... In this context, happy Jazz project H ZETTRIO might be the most normal of them all. Comprised of three members who met in PE'Z, the trio has a penchant for humorous and playful music.
