Zero Order Phase

Jeff Loomis explained in an interview that the album had been written after the end of This Godless Endeavor tour.[4] Loomis wrote two months before starting production.[4] Zero Order Phase was recorded during a month and a half, at the Robert Lang Studios in Richmond Beach, Washington, with producer Neil Kernon and featuring the former Nevermore drummer, Mark Arrington.[5] The choice of Kernon to produce the album had been made several years before while both he and Loomis were working on the third Nevermore album Dreaming Neon Black. Loomis told Kernon that "if I ever did a solo project he would produce it."[4] During the recordings Loomis commented about the album's production, saying: "Being able to do this entire recording with Neil [Kernon] is really amazing as well. We've done some great work in the past, but being able to focus on an entire instrumental record is going to be great".[6]

The album also features several guest appearances. Ron Jarzombek splits solos with Loomis on "Jato Unit", former Nevermore bandmate Pat O'Brien-who joined Cannibal Corpse after recording The Politics of Ecstasy-on "Race Against Disaster", jazz musician Michael Manring on "Cashmere Shiv" and producer Kernon playing a fretless guitar solo on the same track.[7] As Loomis explained in an interview with Komodo Rock, because the guest musicians lived in different parts of the United States, he e-mailed recordings of the rhythm guitar and drums. Each guest recorded his solos at his own home studio and sent the tracks back to Loomis in Seattle.[8]

Zero Order Phase was described as "a good instrumental guitar CD" by About.com reviewer Chad Bowar. He also praised Loomis stating: "excellent guitar skills [...] technical riffs, creative solos and nonstop shredding".[9] Ryan Ogle of Blabbermouth.net said the album was "one goddamned fiery tribute to the instrumental shred lords that have inspired his [Jeff Loomis] playing".[10]

Eduardo Rivadavia of Allmusic wrote: "guitarist Jeff Loomis has unearthed the instrumental guitar hero template that was briefly made popular by Joe Satriani in the late '80s and early '90s,"[11] he also stated that "tracks like 'Shouting Fire at a Funeral,' 'Jato Unit,' and 'Devil Theory' are entrenched in the metallic music ingredients he [Jeff Loomis] is renowned for."[11] 'Azure Haze' and 'Sacristy', were defined as "sweeping ballads"; on the last one, Loomis was again compared with Joe Satriani, Rivadavia stated: "admittedly very Satriani-esque."[11]
