Following that release, Frost Walk With Me / Vitriolic Veracity Vs. The Vortex was released on 7" vinyl via Parasitic Records. The band unleashed their first proper album, Season Of Seance, Science Of Silence, in the fall of 2003. It was recorded with "drone magus" Stephen O'Malley, who assisted in the subsonic mixing.The CD was released in Europe by Lee Dorrian's Rise Above Records and in the US by The Music Cartel, with a limited vinyl version available the following year by Parasitic Records.

The US CD edition was again put out by The Music Cartel. Their third full-length and Relapse Records debut, The Trident was released on April 4th, 2006.

The band performed a handful of live shows in support of The Trident throughout 2006 and 2007, including a month-long European tour just prior to beginning work on a new album. In the latter half of 2007, the band called up Sanford Parker once again to record their next full-length release, Electrocution, at his studio Volume Recording in Chicago, IL. The album was released on March 19th, 2008.
