Souhail Guesmi – also known as Ratchopper – is a multifaceted Tunisian artist; he’s at once a pianist, composer, DJ, record producer, sound designer, experimental solo artist and founder of his record label BLOC C. Starting his journey at just 14 years old, Guesmi quickly found his passion in music: deconstructing tracks he admired and rebuilding them from scratch and eventually crafting his own instrumentals. His early online releases earned local acclaim and led to collaborations with prominent Tunisian artists, underlining his presence in the regional scene.
As he grew as a producer, Guesmi taught himself piano, developing a distinct improvisational and compositional voice. Abandoning an academic path in economics, he pursued music full-time, a decision that has led to international recognition; including the 2023 Paris premiere of his chamber song cycle, Appel de l’Inconnu, at Salle Gaveau.
In 2025, he released regionally charting music that fused Tunisian sounds with contemporary styles, toured globally with Saint Levant while producing on the road in makeshift studios, and contributed to Zeyne’s debut album AWDA. He also released his first solo EP in five years, began developing a computer game linked to upcoming BLOC C releases, and advanced projects with label artists Namiro and Koast. Collaborations with Noisediva, alongside sessions with both established and emerging musicians expanded his diverse and evolving catalogue of work.
