Nastasia Y (formerly known as Stacey Y) has been immersed in Toronto’s bustling multi-cultural music scene since relocating to Canada from Kyiv, Ukraine at the age of 11. Nastasia grew up in an environment surrounded by folk song – her father, the late Kost’ Yerofeyev, was lead singer of the band Ruthenia, and was at the forefront of the Ukrainian independence movement in late 80’s Kyiv. 

Once settled in Toronto, Canada, Nastasia completed her contemporary jazz piano performance degree at Toronto’s Humber College, as well as her Associate of the Royal Conservatory of Music diploma (ARCT) in classical music.



Nastasia Y began her career as a jazz/soul vocalist and keyboardist. In her teens, she was heavily inspired by artists such as Erykah Badu, Stevie Wonder and Norah Jones – artists that heavily inspired her early work. 

As a keyboard player, Nastasia has been involved in Indian, motown, soul, r&b, European folk, and even reggae music groups in Toronto and abroad. By participating in such an eclectic array of genres, she has had the opportunity to share the stage with the likes of Jimmy Cliff, Big Sugar and Ziggy Marley (as part of Kidd Rasta & The Peacemakers), as well as the legendary Shafqat Amanat Ali (as part of the Indo-Pakistani fusion group JoSH).

In her 20’s, Nastasia founded the band DoVira [Do-VEE-rah] (meaning “trust” in Ukrainian), a group that fuses electronic, jazz, rock, and experimental sounds with traditional Eastern European musical elements, as well as its electronic off-shoots (DoVira3 and Balkan Electro Experiment). 

Currently, she is making waves in the Toronto global music scene as a multilingual vocalist. Nastasia has sung in Ukrainian, Polish, Russian, Serbian, Macedonian, Bulgarian, Crimean Tatar, Arabic, Korean, and more. 

‘Nothing is more exciting to me than musical collaboration & juxtaposition of musical traditions. I feel privileged to be able to speak the most beautiful and unifying language of all when I’m performing - the language of music’.


In 2013, under the stage name “Stacey Y”, Nastasia released her debut original album ‘Set The Water Straight’ at the age of 23. On this record, Stacey’s original music blended the genres of r&b, pop, modern jazz, and neo-soul. Rik Emmett (of Triumph) called the album “dynamic, dramatic, hip, stylish and sophisticated”.

In 2017, Nastasia Y & DoVira released their self-titled album ‘DoVira’. Whole Note Magazine referred to it as “world fusion at its best”.


Apart from her artistic work, Nastasia is also the CEO, Founder & Owner of the entertainment company StereoFlavour, which has provided top-caliber live music & planning services for weddings & events since its inception in 2010. Stacey and her team employ some of the most outstanding versatile musicians in Toronto.

Nastasia Y is the featured singer of the Ukrainian arrangement of the Beach Boys’ ‘Wouldn’t it Be Nice’, as heard in the opening scene of Season 3 of the award-winning TV series Orphan Black.


Currently, Nastasia performs solo, as well as with her band, which ranges from folk trio, to a 5-piece rock band formation, to her 9-piece “Slavic fusion” orchestra. She is a member of the all-female Eastern European folk band BLISK, and also performs in a duo with Iraqi-born Ahmed Moneka, exploring music from Iraq to Ukraine. Since the invasion in February of 2022, Nastasia has been heavily involved with fundraising with a group called “Sing With Ukraine” (withukraine.ca). She is currently working on releasing her new fusion album, recorded over the pandemic with KC Roberts (guitar), Marito Marques (drums), Dan Minchom (bass), Anh Phung (flute), Ekaterina (bg vocals), and Juno-award winning co-producer Justin Gray.
