Jim Demos, known by his moniker Hellenica, is a multi-instrumentalist and musician originally from Winnipeg, Canada. He started guitar lessons at the age of 12 and at 18, began his musical journey in the 1990s and 2000s, performing in noise-rock and avant-garde rock bands that helped shape his experimental sensibilities. In 2009, Demos relocated to Montreal, where he began exploring the realms of ambient and cinematic sound, blending electronic textures with a haunting western/Americana guitar style. His performances—staged in venues and theatres across North America, Europe, and Mexico—immerse audiences in atmospheric soundscapes that blur the line between live composition and sonic storytelling. Beyond his solo work, Demos frequently collaborates with musicians in the experimental and improvisational traditions, drawing on genres such as electronic, dark ambient, and drone. He has released over ten albums independently and through international labels including Midira (DE), Blwbck (FR), Somewherecold (US), Machine Tribe (US), and Jeunesse Cosmique (CAN).
