Spastic Ink is an American technical metal band formed in 1993 in San Antonio, Texas, by guitarist Ron Jarzombek following the breakup of his previous band, Watchtower. The band is known for blending complex progressive metal with elements of cartoon music and film soundtracks, drawing inspiration from a range of sources including UK, Rush, Steve Vai, Carl Stalling, and Danny Elfman. The original lineup included Ron Jarzombek, his brother and drummer Bobby Jarzombek, and bassist Pete Perez, both of whom were also members of Riot at the time. In 1994, the band recorded a demo but faced difficulties securing a record deal due to the music being considered commercially unviable. Eventually, Spastic Ink signed a licensing agreement with the German label Dream Circle, which released the cleaned-up and partially re-recorded demo material as the album "Ink Complete" in 1997. The album was reissued in 2000 by Jarzombek's EclecticElectric label, featuring an additional 25 minutes of work tapes as bonus material. Plans for a second album were delayed due to scheduling conflicts, particularly Bobby Jarzombek's commitments to Riot and his later involvement with Halford, the band formed by former Judas Priest vocalist Rob Halford. Attempts to include drummers Sean Reinert (Cynic, Gordian Knot) and Asgeir Mickelson (Spiral Architect) were unsuccessful. During this period of uncertainty, Ron Jarzombek released a solo album titled "Solitarily Speaking of Theoretical Confinement" in 2002, for which he performed all instruments and used programmed drums. Work on a new Spastic Ink album resumed with contributions from drummers Dave Penna and Jeff Eber (Dysrhythmia), as well as Bobby Jarzombek, who recorded additional drum tracks between sessions with Halford. The album also featured numerous guest musicians including guitarist Marty Friedman (ex-Megadeth), vocalist Daniel Gildenlöw (Pain of Salvation), Watchtower members Jason McMaster and Doug Keyser, bassists Pete Perez, Sean Malone (Cynic), Ray Riendeau (Halford, Machines of Loving Grace), Michael Manring (Michael Hedges, Attention Deficit), and keyboardists Jens Johansson (Stratovarius), Jimmy Pitts (Scholomance, The Fractured Dimension), and David Bagsby. The resulting album, "Ink Compatible," was released in 2004 through EclecticElectric and in Japan via Avalon/Marquee. Since the release of "Ink Compatible," there have been no further Spastic Ink projects. In 2005, Ron Jarzombek formed the instrumental technical death metal band Blotted Science with Alex Webster of Cannibal Corpse. Blotted Science released their debut album, "The Machinations of Dementia," in 2007 through EclecticElectric, featuring drummer Charlie Zeleny (formerly of Behold... The Arctopus).
