Respected progressive music outlet The ProgSpace is hosting an exclusive stream of Something Deeply Hidden, the fifth album from English instrumental progressive/math rock quartet POLY-MATH, ahead of its release this Friday on The Lasers Edge.

Something Deeply Hidden was mixed by Mark Roberts, mastered by Chris Muth, and features additional guitar on “Terror Management Theory” by Ben Harris and additional music on “The Universe As An Engine” by C. A. Walters, the latter of which arrives as the album’s lead single. For fans of King Crimson, The Mars Volta, Behold The Arctopus, Dysrhythmia, Battles, And So I Watch You from Afar, and similar acts, POLY-MATH’s instrumental music is prime listening.

Bassist Joe Branton reveals, “Something Deeply Hidden has been a totally different experience for us to write together. It’s the first album we’ve ever co-produced as a band. And, we recorded 90% of the instruments individually in our home studios, which afforded us unlimited time to really focus on each part, try different things. We were really able to hunt for tones, or try new improvised sections without keeping half an eye on the clock in the studio. We’ve been able to dive into our prog and more laid back Ethio-jazz influences much more on this record. It’s still full of big riffs, and what you’d expect from a POLY-MATH album, but we’d like to think it’s more dynamic and a broader sounding more natural record than anything we’ve done before.”

Hear **POLY-MATH’s Something Deeply Hidden early only through The ProgSpace at THIS LOCATION.**

The Lasers Edge will release Something Deeply Hidden on CD, LP, and digitally this Friday, April 10th. Find physical preorders, digital preorders, and presaves HERE.

POLY-MATH will support Something Deeply Hidden with tour dates scattered across the UK and Europe beginning the day of the album’s release, April 10th, running through May 23rd. During the tour, POLY-MATH will also include additional percussionist, Sam Simpson of Memory of Elephants, to better portray the tracks on the new album.

Branton states, “Playing live has always been a really fundamental part of why we love doing POLY-MATH. Getting to tour, and play night after night around Europe, is just the best bit of being a weird, obscure, instrumental band. We’ve got a pretty comprehensive tour this time. We’ve got a solid run of shows in Europe, and then some great UK dates. We’re especially looking forward to our launch show at Oslo in Hackney. It’ll be our biggest ever headliner, and it’s really special to get to do it in such an amazing venue.”

Based in Brighton and London, POLY-MATH is heavily influenced by early classic prog, Ethio-jazz, post-rock, and math rock, having explored different genres and identities over the course of their five albums, two side project lockdown albums, and numerous EPs. The band has morphed through several lineups, initially started as a trio in 2013, formed by guitarist Tim Walters. Originally the drummer of post-rock band Monsters Build Mean Robots, Walters formed POLY-MATH to focus on guitar and explore more expansive instrumental music, joined by bassist Joe Branton and drummer Chris Woollison.

Six months into the band’s casual existence, POLY-MATH was booked to play the opening slot on the second stage of the first ever ArcTanGent Festival in Bristol, UK, a festival that today has become one of the UK’s premium avant-garde music events. Following the success and subsequent support that ArcTanGent afforded the band, POLY-MATH switched it up a gear, and started working more seriously on recording and touring.

In 2018, POLY-MATH crowd funded their album, House Of Wisdom | We Are The Devil, allowing fans the opportunity to send in voice notes from selected texts to be manipulated and used in the final record. Shortly after this, the band expanded to a four-piece, with the addition of keyboardist Josh Gesner; an American multi-instrumentalist who had recently relocated to the UK. While the band started work on their 2022 release, Zenith, they also took on saxophonist Chris Olsen, expanding the band to a five-piece, although only temporarily for that album.

In 2024, POLY-MATH began work on their new album, Something Deeply Hidden, alongside the preliminarily released EP, The Halting Problem. These two releases are the first to include abstract expressionist artwork created by guitarist Tim Walters. Both the album and EP are the first releases to be largely recorded by the band themselves. In style, they both move away from the formulaic structure of POLY-MATH’s previous work and include a greater focus on improvisational solos and expansive percussion.
