Onalea is currently performing as Hecate in New York City in the hit Off Broadway show Sleep No More.

As a consummate crossover artist, Onalea's original work is a unique blend of music and the theatrical. As a performer she has worked in both the traditional and the avant-garde playing roles on the stage, screen, and in cartoons. An accomplished vocalist, she has sung with everything from solo piano to chamber ensembles, symphony orchestras, and big bands. She has recorded four CD's ranging from big band to jazz standards, electronica to original material.

As a theatre artist she has performed numerous roles across Canada, including 7 seasons as an ensemble member with the award-winning  Canadian physical performance theatre company One Yellow Rabbit,  creating many original characters and starring as Sylvia Plath in Sylvia Plath Must Not Die. 

Select Roles include: Into the Woods (Cinderella); The Mystery of Edwin Drood (Drood); Assassins (Squeaky Fromme); Falsettos (Cordelia); and Bernstein's MASS  with the Calgary Philharmonic Orchestra - Hans Graf conducting (Mezzo Soprano/Blues singer). 

With Dandi Productions, she co-created and performed shows as an actor, singer and puppeteer, with symphony orchestras internationally including the Hallé Symphony - the oldest orchestra in the UK.  Most recently Dandi toured to Australia to perform with both the Adelaide & West Australian symphony orchestras.

Onalea's original pieces REQUIEM FOR A LOST GIRL:  A Chamber Musical About Homelessness and BLANCHE: The Bittersweet Life Of A Wild Prairie Dame  premiered in New York City as a special events of the New York Musical Theatre Festival.  BLANCHE was named a top 20 show in New York in 2011 by the Huffington Post.  REQUIEM will be performed with the Vancouver opera in May 2018.
