As a teenager, Baratz became a regular on the Pittsburgh jazz circuit, playing with the likes of legendary hard-bop drummer Roger Humphries, bassist Dwayne Dolphin and trumpet giant Sean Jones. She honed her craft with the guidance from the best of the Iron City's local musicians, as well as a brief interlude with saxophonist Branford Marsalis. Intent on continuing Pittsburgh's jazz legacy, Baratz moved to New York at 19 to attend the New School for Jazz and Contemporary Music on a scholarship.
Early in 2006, Baratz emerged as a band leader upon meeting trumpeter Corey Wilkes. Wilkes, the Chicago native with his own searing polish, joined her on stage in Pittsburgh for Baratz’s first live recording. This would mark the start of a long-running musical collaboration between the duo. Baratz hooked up with Wilkes in Chicago to play with his quintet, performing at Millennium Park as a special guest with the Chicago Young Lions Project, alongside the legendary Jimmy Cobb & Von Freeman.
In New York, she met trumpet virtuoso and producer Maurice Brown. Brown was impressed by Baratz’s playing and magnetic personality. She joined him in the studio to record "Mobetta & Soul'd U Out: The Official Mixtape" (Brown Records), Brown’s stellar 2007 release. 2007 was a busy year for Chelsea: she played on Aretha Franklin's album, "Jewels in the Crown” and performed at the Sisters in Jazz collegiate all-stars IAJE conference in New York, the Mary Lou Williams Women in Jazz Festival at the Kennedy Center in Washington, D.C. and the Costa Rica International Jazz Festival in San Jose, Costa Rica. In 2008 she was featured as an artist & composer on Wilkes’ album, "Drop It" (Delmark Records).
“I'm a messenger, this is a movement. I'm on a mission for this music. I've traveled all over searching for this feeling in the music. That search is what first took me to Chicago, what brought me to Corey Wilkes, brought me to NYC, lead me to Maurice Brown, who’s at the forefront of this new Soul Jazz movement. It lead me to New Orleans to go down there in the grimiest of situations to immerse myself in the music I'm in search of.”
Baratz maintains a busy performing schedule, having played with Louis Hayes, Nicholas Payton, Christian McBride, the Roots, Soulive, Dirty Dozen Brass Band, DJ Logic, Roy Hargrove, Jeff "Tain" Watts, Vincent Herring, Benny Green, Branford Marsalis, Robert Irving III, the Orrin Evans Quartet, and Evans' Captain Black Big Band, and the lightning-hot soul jazz quintet, the Maurice Brown Effect.
Her life is her music.
