[5] At Tappan Zee High School she performed in many of the Drama Department's theatrical productions, including Gypsy (in the role of Louise),[6] Kismet,[7] Dracula,[8] Don't Drink the Water,[9] Anything Goes, and Cabaret.
[12] Mason's extensive Broadway career began in 1987, when she made her debut, billed as 'Kim Freshwater,' as the statuesque, leather-clad nightclub owner in the short-lived musical Late Nite Comic.
Significant roles followed as the mourning mother Mrs. Kresinsky in Paul Simon's The Capeman, the doomed Lucy Harris in Jekyll & Hyde replacing Linda Eder, and later playing the hardened Velma Kelly opposite Brooke Shields' Roxy Hart in Chicago, directed by Walter Bobbie.
Other roles include Joanna in Trevor Nunn's American premiere of Sunset Boulevard with Glenn Close at the Shubert Theatre in Los Angeles in 1993.
Mason can be heard on Broadway cast recordings of The Will Rogers Follies, How To Succeed in Business..., The Capeman, The Stephen Schwartz Album and Girl from the North Country.
[15] Mason, blessed with "...a celestial voice" (Los Angeles Times), was a guest vocalist on Rubén Blades’ double Grammy-winning cd Mundo in 2002 with her rendition of "Danny Boy".
[15] Luba Mason has been called "a powerfully emotional song interpreter...a much needed dose of uniqueness in an industry where bland pigeonholing is an art form in itself."
Exploring Brazilian music further, she collaborated with Renato Neto and wrote or co-wrote most of the songs for her cool jazz/pop/Brazilian cd Krazy Love (2009),[11] described as "a voice as big and rich as a star filled sky," (Jazz Times).
Most recently Mason and her husband Rubén Blades performed together at Radio City Music Hall in Paul Simon's sold-out benefit concert for the Children's Health Fund's 25th Anniversary[20][21] and in 2014 at Jazz at Lincoln Center with Wynton Marsalis and his band.
[2] Mason's film and television work includes Abuse, The Ten Commandments: The Musical, Law & Order, NYPD Blue, Another World, One Life to Live, New York Undercover, Now and Again, Raines, Person of Interest, and Forever.
