Vitro was exposed to jazz and it became her genre of choice after moving to Houston, Texas in the 1970s. Ray Sullenger discovered Vitro and presented her to the Houston jazz community where she sang frequently with Arnett Cobb. She worked for two years at the Green Room in Houston with her group Roseanna with Strings and Things and hosted a radio show on KUHF-FM. The band performed with Oscar Peterson, Bill Evans, Tommy Flanagan, and Keter Betts. Cobb, Peterson, and Sullenger encouraged her to dedicate herself to jazz.
In 1978, she moved to New York City with guitarist Scott Hardy and began to study with Gabor Carelli, a professor from the Manhattan School of Music, and began to perform with Kenny Werner and Fred Hersch. She sang with Lionel Hampton and toured with him. She appeared at The Blue Note, Iridium, Birdland, and Dizzy’s Jazz Club at Lincoln Center. She appeared with Steve Allen at The Town Hall at The Apollo Theater and recorded an album of Allen’s songs. In 2005 she performed and recorded with the Kenny Werner Trio at the John F. Kennedy Center in Washington D.C.
She has worked with Kenny Barron, Christian McBride, Elvin Jones, Gary Bartz, Kevin Mahogany, and David “Fathead” Newman, all of whom have appeared on her recordings. She was a guest on Marian McPartland’s radio program Piano Jazz. Her album The Music of Randy Newman received 4 1/2 stars in Down Beat magazine and a Grammy nomination for Best Jazz Vocal Album in 2012.
