through stylized arrangements and improvisation. Over time the ensemble expanded its repertoire with over 300 transformed works from jazz, Broadway, American folk songs, Klezmer, Yiddish theater, Latin Jazz, Mideastern, Mediterranean, and classical music. Kula often uses archival music from collections across the globe as source material  for creating new  compositions.

In 2009, KCJO released its award winning CD Beyond the Tribes, which was selected in 2011 by the Library of Congress (LOC) for inclusion in the Copyright Acquisitions Division. The LOC cited this recording as representative of an important American culture that would "enrich the collections." In 2012, the band released its second studio album Klezmerology and in March 2016 released their third album called JubanoJazz, celebrating the fusion of Latin Jazz and vintage American Klezmer melodies.  From 2011 to 2014, Kula led KCJO on concert tours to California, Arizona, and Rhode Island. In 2015 KCJO was invited to perform in Canada at the Ashkenaz Festival in Toronto and Montreal Jewish Music Festival. In 2018 the band collaborated with the Grammy winning Latin Jazz flutist Nestor Torres in a concert for Jewish Federation of Broward in Florida.
