OSI

OSI is 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 Steven Wilson, Mikael Åkerfeldt, Sean Malone, Joey Vera and Gavin Harrison.

Matheos recruited Moore and Dream Theater's then-drummer Mike Portnoy 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 in style to Matheos' work in Fates Warning. Moore changed the music's direction, incorporating electronica into the original progressive metal sound. The band's debut album was released by InsideOut Music in 2003.
