BobLeader BOB SCHWARTZ took up the flute in 3rd grade. As a high school junior he was all-Nassau-County (New York) playing Mozart. He took up sax to join the dance band; by high school he and pal David Berger were the featured soloists and writing big band instrumental and vocal arrangements. While studying at Cornell, Bob played lead alto, tenor, and baritone sax with the Ithaca College Jazz Lab, and co-led with Berger a quartet that featured pianist Andy LaVerne. As David went on to become a leading New York-based composer, arranger, and conductor, Bob joined the Justice Department and then became a lawyer-lobbyist. He stopped performing in public but produced albums for David’s bands, I Had The Craziest Dream: The Music Of Harry Warren, named the Tribute Album Of 2008, and in 2010, Sing Me A Love Song – Harry Warren’s Undiscovered Standards, featuring Freda Payne and Denzal Sinclaire with the David Berger Jazz Orchestra.

After years of playing in clinics and masterclasses, Bob formed BSQ. Starting with private events, BSQ entered jazz clubs and restaurant and hotel venues.


RobRALPH CORNWELL started out playing drums in middle school in Texas. He later took up the vibes while in high school, where he was awarded a scholarship to a Jamey Aebersold Jazz Workshop after Clark Terry heard him perform on the vibraphone at a jazz ensemble contest.

He studied percussion at the University of North Texas. After graduation he concentrated mainly on drums. Over the years he has performed on drums with the Nelson Riddle Orchestra, Mark Murphy, Dan McMillion's Jazz Orchestra, Helios, Tampa's Late Night Brass and the George Carroll Big Band. He is currently the house drummer for the emPower Music and Arts Annual Posi Awards show in Tampa.

After some significant life changes, including a move to the Washington D.C. area in 2013, he decided to shift his focus to performing almost exclusively on the vibraphone. He has recently studied advanced vibraphone techniques at the University of Delaware Vibraphone Workshop with Tony Miceli and in master classes with Jeff Antoniuk and Fred Hughes.

As a vibraphonist he has performed with Clint Strong, The Difficult Run Jazz Band, art openings, private parties and the Bob Schwartz Quartet. Ralph's major influences are Gary Burton and Milt Jackson. He lives in Silver Spring with his wife Linda.

NinaNINA has been singing the standards since she was a kid and she is grounded in classic renditions by jazz singers such as Anita O’Day, Ella, Mavis Rivers, and Blossom Dearie.

As a painter and graphic artist her initial roll was to design the BSQ logo, website, and the artwork for our CDs, as well as for the prize winning CDs that Bob has produced for the David Berger Jazz Orchestra. When a restaurant owner asked BSQ for some vocals, Nina stepped into the limelight herself. She studies voice with Alison Crockett.
