In the best numbers, Juilliard-trained Vlahos covers well-known, though not often-heard tunes, giving them a dark edge. Most memorable are Cab Calloway’s “Minnie the Moocher” and John Lennon’s “Jealous Guy.”

Stephanie established herself as a recognized performance artist earning the monicker of “the moonlighting Diva” by the Associated Press for her direction of and performances in cabaret-influenced showcases devoted to the music of European cabaret and music hall. Although best known as a Kurt Weill interpreter, her whimsical tribute to our love of film noir, The Gangster Hour, was hailed by Variety as a “Cotton Club meets the Maltese Falcon…but what really sells is Vlahos and her incredible voice…”

Unlike many opera stars trying to expand into pop styles, mezzo-soprano Vlahos doesn’t over sing most of her material; that’s a definite plus.
Elle Qui Chante

Stephanie Vlahos, mezzo-soprano with the Los Angeles Music Center Opera, has been moonlighting for the last couple of years with programs of international pop music, notably French cabaret songs (in last year’s show “Elle qui chante”) and the music of Kurt Weill. “Even More Weill,” currently playing Wednesday nights at the Gardenia in Hollywood, is her second Weill program, following “Weill Thoughts” at the Largo two years ago. It’s not as ambitiously staged as “Elle qui chante,” which featured dancers and a small band, but retains many of the theatrical elements that set Vlahos’ act apart from most cabaret singers.
