Simon Sammut began his musical journey at a young age, initially studying under his father Joseph Sammut, himself a respected bass player. He quickly advanced in his musical education and soon established himself as a versatile and sought-after bassist. His early performances spanned rock, blues, soul, and funk, eventually expanding into jazz and upright bass as he developed a broader artistic voice.

A fluent reader with eclectic musical taste, Simon has performed across a wide spectrum of genres and ensembles, collaborating with leading musicians and appearing in numerous high-profile events. His versatility has seen him perform with a range of bands, jazz ensembles, and orchestras, including the Malta Philharmonic Orchestra.

In addition to his career as a performer, Simon is active as a composer, arranger, producer, and music educator. His creative output reflects a deep curiosity for musical storytelling and cross-cultural collaboration.

Simon released his debut solo album BaSSic Attitude in 2011, a project in collaboration with multi-instrumentalist Alexander Kuzmin. In 2017, he followed up with Crossing, an interdisciplinary work featuring twelve original compositions and accompanying paintings by Maltese artist Anthony Catania, exploring the theme of personal and cultural transitions.

In 2019, he collaborated with Mexican musician Omar Vázquez on Gravity, an album that brought together musicians from Malta and Mexico. The project blends jazz fusion, funk, Latin, and world music, and was premiered live in Cuernavaca, Mexico. It was the result of a cultural exchange facilitated by the Secretaría de Turismo y Cultura Morelos and the Centro Morelense de las Artes.

In 2024, Simon released his fourth album Visions of Transcendence, an ambitious project featuring international collaborators and an expansive sonic palette that fuses jazz, world music, and cinematic influences. The album explores themes of unity, transformation, and spiritual reflection through instrumental storytelling. It was funded in part through a successful crowdfunding campaign and has received praise for its evocative compositions and rich production.
