The group has always been a project of members from various bands, first comprised of Phil carnes (Desolate Angel), Clarence Osbourne (Mercury Rising), Keith Menser (Mystic-Force), and Doug Readmond (20 on the Hype). In 1996, a Delusion promotional sampler was released to mags and radio giving the band its first attention internationally. Struggles with lineup changes between 1996-1997 caused the band to re-release the songs from the promotional sampler on a 4 song EP compact disc titled Discharge, when Clarence Osbourne left under contract with the band Mercury Rising who had been signed, and Walt Downey (Surreal) joined the group as vocalist. That EP promotional release in 1997 led to the band being noticed in the European metal market and opened up several opportunities. Between 1998-2000 Delusion appeared on several international compilation and tribute CD's, including the double compact disc Children of the Damned : A Tribute to Iron Maiden with a blazing rendition of "22 Acacia Avenue". In 2000, Delusion focused on completing a full-length LP compact disc which was released through Ravenhurst Records in 2003-2004 to over 500 stores in 28 countries. In the midst of this release, the group was forced to defend its trademark in a case with the USPTO lasting from 2003-2007, in the the case of Delusion vs. Dillusion. Delusion's trademark rights were upheld in 2007 and Phil Carnes began writing material for a new Delusion album in 2008. The trademark dispute took its toll on the group and members Walt Downey and Doug Readmond did not return for the second album, prompting a search for a new singer and drummer. In 2012, vocalist Nick Horner and drummer Trevor Ray joined the group. The band has presently completed the 12 songs to appear on their new album The Temple Divine. This time Delusion returns having spent the past few years developing a unique sound for the group to take their music to a new level.
