Now celebrating his 35th season as the founding music director of The Chicago Bar Association Symphony Orchestra, Katz has led Chicagoland’s unique all-lawyer ensemble nearly two hundred times during his long tenure, in repertoire ranging from Trial By Jury, (the first performances of Gilbert & Sullivan’s courthouse operetta ever presented in a working courtroom with a cast and orchestra made up entirely of legal professionals) to Beethoven’s Symphony No. 9, as well as major orchestral and choral-orchestral works by Brahms, Britten, Bruckner, Dvorak,  Haydn, Mahler, Mendelssohn, Mozart, Poulenc, Respighi, Rossini, Shostakovich, Tchaikovsky and scores of others.

Katz and the CBASO, joined by the CBA Chorus and guest choirs, nearly three hundred musicians in all, presented Orff's Carmina Burana to a capacity crowd at Orchestra Hall, Chicago, in celebration of the CBASO's 25th season in 2011. The ensemble returned to Symphony Center for Something Wonderful!, an all-Rodgers & Hammerstein concert, in spring 2015, and made a third appearance at Symphony Center in a program called “Ode to Joy,” in June 2019.
