Researched musician profile
About Hidenobu KALTA Otsuki
JZ Brat’s musician biography records Otsuki’s Yokohama upbringing, early work as a professional drummer and instructor, and expansion into composition, arranging, production, and music for games and commercial media.[1]
The biography distinguishes his leader unit Vertical-Engine from work with TKY, Jazztronik, and other projects. It dates the Vertical-Engine album to 2008 and documents the group’s 2011 Detroit International Jazz Festival appearance.[1]
Authorized performance archives show the drummer in two contrasting settings: a leader date at Blues Alley Japan and a complete organ duo with Daisuke Kawai.[2][3]
