In his compositions, Guillérm reveals the theme of mental illness and its impact on a person. Art work 'Demon' is a conceptual work based on his own experiences and feeling. EP 'Demon' was recorded a month before the artist was admitted to a psychiatric hospital for treatment of symptoms of depression, paranoia, PTSD and personality biopolar disorder.  

In his release, Guillérm with the skill of the creator shows the vulnerability of humans to the challenges of society and their detachment from these problems. Human mental health is the most important component of all health and we must take care of those who have these problems and understand their changes in mental evolution. 

Guillérm's velvet voice hides in the harmonious piano music with classical motifs. He captures the flow of the melody and recites his thoughts, transforming them into exquisite musical works. In the music videos, the artist is looking for himself walking along the sea coast, listening to vinyl, smoking cigarettes. He is sad and closed in on himself. He is completely immersed in his inner world and invites us to see in it the thinking author. Watch the music video 'Demon' from Guillérm below on YouTube.
