[8] Bonifassi appeared as a guest vocalist on Deweare's album High Class Trauma (2006),[9] and she is one half of the electronic music duo Beast.

[12] In 1997, Bonifassi met her now ex-husband,[4] Québécois composer Benoît Charest, while singing Jimi Hendrix covers at a Montreal jazz club.

[7] In the late 1990s, Benoît Charest and Montreal DJ and musician Maxime Morin became co-owners of Ben & Max Studios – a company specializing in jingles and soundtracks.

The album included the hit single "No Heaven" which is a soulful and bluesy song set against heavy dance beats and noisy guitar riffs.

[16] In 2008 the pair recorded a version of 1957 Screamin' Jay Hawkins hit "I Put a Spell on You" to be used as the theme song of the Québécois film Truffe.

[11] Bonifassi joined forces with percussionist, record producer, and fellow French expat Jean-Philippe Goncalves, to form the band Beast.

Canadian singer-songwriter Simon Wilcox also assisted Bonifassi (whose native tongue is French) with Beast's lyrics, which are all performed in English.

[19] Citing lagging album sales, frustration with the record industry, the tiresome effects of touring, and familial commitments (Bonifassi's son was 9 years old at the time of the split), the bandmates said they would be working separately on their own local projects.

[24][25][26][21][27] In 2014, Bonifassi released a self-titled CD in which she interpreted traditional songs of slaves and prisoners, plus two original cuts, "Working It Down" and "How Does It Feel."
