Although I have been performing solo piano since 2006, an improvisation recording made in 2022 became a turning point. I began actively incorporating rhythmic pattern–based techniques and A-tonal approaches into my playing. Following the release of my 2026 album Everything is Alive, my performances have continued to evolve in alignment with the ideas and aesthetics of that record.

DA FLUFFY

2020

by Tetsuro Hoshii

I directed my first film called Da Fluffy, starring Jason Rosenberg. It's a part of the project of Film Force. 3 hours of makeup with YouTube tutorial, 2 hours of shooting, few days of composing music and few months of editing (includes minor injury of my arm from Foley)! This project really saved my quarantine life in May and June of 2020.

Film Force is the unique collaboration of several film directors based in New York, making their own short film, but using exactly the same script. This time, 7 short films by 7 different film directors, but all films have the same script, directed differently.

HERE IS THE REST OF FILM FORCE SHORTS

(It's same dialogue! But direct differently)
