HISTORY
Blind Illusion was formed by-15 year old Mark Biedermann, along with drummer Bret Hern and bassist Les Claypool. The band's earliest sound had been musically rooted as progressive metal, with Biedermann citing as his main inspirations Rush, King Crimson, Led Zeppelin, Black Sabbath, Van Halen and Jethro Tull. However, external input from later musicians, many with ties to the Bay Area thrash scene would add a Thrash Metal direction to the band. In 1983 live recordings traded by fans with songs like "Death Noise", "Darkness", "Kamikaze", "World That's an Illusion", "Helter Skelter (Beatles)", and "Concerto" were part of their set list. Blind Illusion had already released 2 demos by 1983. During this period, Blind Illusion played extensively with bands such as Exodus, Testament, Death Angel, Metallica and Possessed playing shows throughout the area through the 80's. Mark Biedermann took over vocal duties in place of former singer Dave White who left the band to join Heathen after the release of Blind Illusion's third demo Trilogy of Terror that was produced by Metallicaʼs guitarist Kirk Hammett. The first demo with Mark Biedermann as vocalist was the Bloodshower Smash the Crystal demo.
The band also added second guitarist John Marshall (later of Metal Church) who, in 1987, would be replaced by guitarist Larry LaLonde, formerly of pioneering death metal band Possessed. In the same year, Blind Illusion signed a record deal with Music for Nations on their Under One Flag Record/Combat division, with whom the band recorded their debut record in 1987, The Sane Asylum, which was released in 1988. The album was considered a Thrash Metal classic, featuring tracks such as Vengeance is Mine, Death Noise, Kamakazi, Smash The Crystal, Blood Shower etc.. At the same time Mark Biedermann worked with producer Sandy Pearlman in 1987 contributing rhythm and guitar leads on four songs for Blue Öyster Cult on their Imaginos album along side Joe Satriani and Robbie Krieger from The Doors. Metal Mind Productions re-distributed a limited edition pressing of The Sane Asylum in 2007 as the 1988 Combat Records released version of the album had been long out of print.
Mark Biedermann reformed Blind Illusion in 2009 with a new-lineup, releasing Demon Master on July 7, 2010. In December 2013, Biedermann bumped into DRIʼs Bass player and Metal Photographer Harald Oimoen in Berkeley, California. Harald called drummer and long time friend Cire to join. World in Sound Records out of Germany re-mastered and released The Sane Asylum in March 2015 with bonus tracks from"Trilogy of Terror" demo.
After the lukewarm reception to Demon Master. In April 2017 Guitar Legend Doug Piercy who has known Mark since 1982 joined Blind Illusion. Tom Gears replaced Harald O on Bass. After a successful European Tour in the Summer of 2017 Blind Illusion found itself back in rehearsals working on their new EP 2018. In 2018 Blind Illusion embarked on their second European Tour and were featured at the Keep It True Festival in Germany. After the tour Blind Illusion hit the studio with James Boblak mixing/engineering and mastered by Legendary Guru Dave Collins. "2018" EP Produced by Doug Piercy and Blind Illusion.
In 2019 the band scheduled the Slam Asylum 2019 tour of Germany, Belgium and the Netherlands with Bestial Invasion. After returning from the tour the band recorded their newest album 'Wrath of the Gods' released October 7, 2023 under Malevolent Entertainment distributed by Hammerheart/Napalm/Nuclear Blast.
