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 throught the 80's. Mark Biedermann took over vocal duties in place of former singer Dave White who left the band to join Heathen and released a third demo Trilogy of Terror that was produced by Metallicaʼs guitarist Kirk Hammett.

 In 2019 the band reached out to Serg MP the bassist for Bestial Invasion to find a touring partner in Europe. He introduced us the band to Fusion Bomb from Luxembourg. The two bands hit it off right away and scheduled the Slam Asylum 2019 tour of Germany, Belgium and the Netherlands. Special thanks for booking the tour are given to Jochen Boellath from Daredevil Records. Many thanks to one of the bands biggest supporters Paul van Rijswijk, guitarist of the Dutch Heavy Metal band Emerald for booking Blind Illusion on the Heavy Metal Maniacs festival in Amstelveen.

 After returning from the tour the band is focused on releasing a new album of original music for release in 2020!
