Darrell Katz leads the 20 piece Jazz Composers Alliance Orchestra in a program including his improvisational cantata, "Wheelworks," due out on the Leo Records release Why Do You Ride, featuring vocalist Rebecca Shrimpton. Also on the bill are a new composition honoring recently retired Berklee faculty member Phil Wilson, featuring faculty members Helen Sherrah-Davies on violin and Vessela Stoyanova on marimba. Katz and the JCA Orchestra have been presenting new music in the Boston area since 1985.
