A Bass Dream Realized: Steve Di Giorgio & Jeroen Paul Thesseling’s Vision Comes to Life on “Tetradom”

For years, we’ve eagerly anticipated music from Quadvium, the two-bass band created by fretless metal masters Steve Di Giorgio and Jeroen Paul Thesseling. We finally have the details of their debut album and even a track to dig in on.
Tetradom will be released on May 30th on CD, LP, and digital formats. The seven-song effort will also feature Dutch drummer Yuma van Eekelen (Our Oceans, Pestilence) and American guitarist Eve (Myth of I, Kaathe) for a lineup that delivers a “heavy aural offering and a full vocabulary of high-level constructed pieces.
In announcing the album, Di Giorgio and Thesseling shared a statement.
“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,” the two bassists write. “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.”
