"Tetradōm" is the debut album of the instrumental progressive metal-fusion quartet Quadvium, half in California - half in the Netherlands, founded in late 2019 by American bass player Steve Di Giorgio (Testament, Death) and Dutch bass player Jeroen Paul Thesseling (Obscura, Pestilence).

Steve Di Giorgio and Jeroen Paul Thesseling are both innovators in bringing a different style of fretless bass 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 Eve (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.

"We had an intention many many years ago to make some music together… to feature two predominately multistring fretless bass players playing in duet form," Quadvium bassists Steve and Jeroen comment. "That is to say, neither being «rhythm bass & lead bass» nor some trading off hot solo licks mess. But easier said than done! While hanging out, we exchanged some thoughts about how it would be to form a group to support our bass-ic needs. At that time it was just a spontaneous idea, but over the years the topic was brought up again and again. This vision was blurry at best and it took us a long time to not only imagine how to feature the bass in this way, but more importantly – who would share in this concept with us. Yuma is an old acquaintance and lucky for us, he needed this project to add to his list of a thousand others! But having a drummer that understood that 2 bass players would be filling the sonic spectrum, he was undaunted in contributing the backbone as well as keeping our outlandish ideas in check. After a long search for the next musician, a gold mine was found on Instagram reels by the name of Eve. Some of the most insane guitar (and bass!) videos we ever saw inspired us to ask if this was a project worth joining… not only did we have our final member aboard, but a studio genius and the main composer of this strategy we had so long ago, who brought it all together and focused everything into the album we are so proud to share with you now. Thanks to the solid support from Agonia Records for supporting our dream and making this album a reality! Fans of instrumental progressive metal fusion – and fretless bass! – will surely enjoy these musical journeys."

"Tetradōm" was recorded and produced by Eve and co-produced by Yuma van Eekelen. The album was mastered by Dereck Blackburn at Quiethouse Recording. Travis Smith (Amorphis, King Diamond, Cynic) created the album's artwork and layout.
