Black Ox Orkestar is a quartet that formed in Montreal, Quebec in 2000 who play modern Jewish diasporic music that draws influence from Klezmer, Romani, Arabic, Balkan and other East European traditions alongside indie rock, experimental folk and avant-jazz. The band interprets traditional tunes and composes originals sung primarily in Yiddish.
The members are Thierry Amar, Scott Gilmore, Gabriel Levine and Jessica Moss; they were also active in various other notable Montréal bands in the 1990s-2000s including Godspeed You! Black Emperor, Thee Silver Mt. Zion and Sackville. Thierry Amar continues to play in Godspeed You! Black Emperor and Jessica Moss pursues a solo practice rooted in electroacoustic violin composition.
Black Ox Orkestar released two albums on Constellation Records in 2004 and 2006. The band reunited in 2021 and announced a new album Everything Returns on 20 October 2022, which was released on 2 December 2022.
