Modern applications in the liberal arts as curriculum the quadrivium is considered to be the study of numbers and their relationship to space and time. Arithmetic is pure number. Geometry is number in space. Music is number in time. Astronomy is number in space and time. Quadvium is through composition, our interpretation of this soundscape.

QUADVIUM, half in California – half in the Netherlands, is an instrumental progressive metal-fusion quartet founded in late 2019 by American bass player Steve Di Giorgio (Testament, Death) and Dutch bass player Jeroen Paul Thesseling (Obscura, Pestilence) both innovators in bringing a different style of fretless playing to metal. Launching a band with two predominantly multi-string fretless bass players is no common occurrence, and the bass-duo felt they needed to take very special and deliberate time to get the right alignment with who is participating and what will be the end result - meaning the right sound and composition to represent this rare vision. Over time, together with Dutch master drummer Yuma van Eekelen (Our Oceans, Pestilence) and American guitar virtuoso/ composer Jennings Smith (Myth Of I, Kaathe) – whose contribution and expertise play a huge part of QUADVIUM – the music began to take shape. The line-up is just the right blend to mix the delicate balance of such a heavy aural offering and a full vocabulary of high level constructed pieces. QUADVIUM is currently finalizing their long-awaited debut album, set to be released in Autumn 2024 via Agonia Records and set to include artwork by Travis Smith (Amorphis, King Diamond, Cynic).
