to David Bursztein's Shtetl...



Actor, author, director, singer and composer.


From the stage of the Comédie Française

to Welt Orchestra ...

As many of my generation's fellows, I'm in this kind of unique and isolated connection to this culture. My wish it to humbly bring up a testimony of this lost word which lives in my inner self. 

Yiddish : this very language which I merely speak. This language made of fragments, fragments of "Yanglish" and " Frenddish", contractions of English and French, memories of Yiddish.

Welt's musicians
Dibbouks, humor, songs
& co...

It takes no less than three Dibbuk to mention the Shtetl's memory and carry us over the past with humor, poetry and sometimes solemnity...

Music, bands and the first production company.

Over ten years of shows, venues, concerts and balls all over the world.

Talentuous musicians, fun and appreciative audience...
