Cold, mechanical precision meets human vulnerability. A blend of heavy guitar riffs and glitchy electronica for late-night focus or solitary urban walks.
OSI sounds like the intersection of a high-tech laboratory and a rainy city street. It is music built on the friction between Jim Matheos's heavy, rhythmic guitar work and Kevin Moore's detached, electronic soundscapes. The result is a sound that feels both incredibly dense and strangely spacious, characterized by mid-tempo grooves that never quite explode into typical metal histrionics, opting instead for a steady, hypnotic pulse.
What makes them truly distinctive is the 'audio Rorschach' approach to songwriting. The vocals are delivered in a hushed, almost conversational deadpan that sits deep in the mix, surrounded by found-sound samples, radio chatter, and intricate synth programming. It is a studio-first project where the editing process is as much an instrument as the guitar or drums, resulting in songs that feel like they have been meticulously assembled from disparate parts.
Start with the album Blood. It represents the peak of their collaborative chemistry, featuring the surgical drumming of Gavin Harrison and a perfect balance between their metallic foundations and electronic experimentalism. It is the ideal entry point for anyone who finds traditional progressive metal too flashy and electronica too cold.
OSI was an American progressive rock band, originally formed by Fates Warning guitarist Jim Matheos in 2002. Chroma Key keyboardist and vocalist Kevin Moore is the only other full-time member of the band. The collaboration may be considered a studio project, as its members and contributors write and track most of their material independently, sharing and developing tracks long-distance, only coming together at the end of the process for mixing and additional tracking. The band's name is a reference to the Office of Strategic Influence, a short-lived American government agency formed in 2001 to support the War on Terror through propaganda. The band has featured a number of guest musicians on its albums, including Sean Malone, Steven Wilson, Mikael Akerfeldt, Joey Vera and Gavin Harrison. Matheos recruited Moore, Dream Theater's drummer Mike Portnoy, and Sean Malone (Fretless Bass and Chapman Stickist) to perform on what was originally planned to be a Matheos solo album. Matheos and Portnoy originally planned to produce a progressive metal album similar to Matheos' work in Fates Warning, however Moore's impact changed the music's direction and genre, incorporating electronica into the original progressive metal sound. The band's debut album was released by InsideOut Music in 2003. OSI was originally intended to be a one-off project, but Matheos and Moore found they both had gaps in their schedules so produced a follow-up. Free was released in 2006, with Portnoy returning to play drums as a session musician rather than a full band member, due to personal and musical differences between him and Moore. Blood was released in 2009, with Porcupine Tree drummer Gavin Harrison replacing Portnoy. The fourth album Fire Make Thunder was released in 2012 by Metal Blade Records, with Harrison once again on drums.
