The concept of Brave Saint Saturn (or BS2) began in 1995, but it was only during the final years of Five Iron Frenzy that Reese formalized the band with FIF bandmates Dennis Culp and Keith Hoerig. BS2 is primarily a studio project and has been described by Roper as an outlet for songs that didn't fit Five Iron Frenzy's musical style. The band and some fans put forth a new term, "astro-rock", to describe the music of Brave Saint Saturn, which is fundamentally rooted in synthesizer-bathed post-punk and haunting ballads. The band also describes themselves as being the "supersonic-philharmonic", in reference to their blending of rock music, classical instruments, synthesizers, and beat loops. The third album of the "BS2 trilogy," "Anti-Meridian", was released on September 15, 2008. During an interview on October 15, Roper indicated that this may not be the last album from BS2.
