Machine Head, Soulfly and Medication Machine Head formed in October 1991, with Mader on lead guitar,
Robb Flynn on vocals and rhythm guitar,
Adam Duce on bass and
Tony Costanza on drums. He played with Machine Head through two albums until early 1998. After Mader's six-year run with the band, he joined
Soulfly where he filled the slot as guitarist for their 1998 world tour. Mader's union with Soulfly was short-lived (eight months) and the only track he technically recorded with them was one of the remixes for
Quilombo. Wanting to once again pursue his own projects, Mader left Soulfly in January 1999. Post Soulfly, Mader formed Los Angeles rock band
Medication with
Whitfield Crane (formerly of
Ugly Kid Joe). Due to a series of internal issues, Medication disbanded in February 2003. Although the band opened for
Tesla and
Hed PE, made a demo co-produced by
Junkie XL they were never signed to a label. The song "Inside" (previously titled "Save Me") was featured in the commercial for
Max Payne, the trailer for
The Butterfly Effect 2, and in the movie
Never Back Down 2: The Beatdown. The instrumental of the song "Fall Again" is featured in ''
MotoGP '07 soundtrack. The song "Denial" is featured on the Scream 4'' soundtrack. In 2017, Mader dismissed Stereo Black as "just a studio project" that started for the purpose of
sync licensing. After having some success with that, members tried to turn it into a band, but then he realized he wanted to become a full-time producer instead.
Return to live music and further production work Mader announced his new project,
Once Human, in May 2015, which features newcomers Lauren Hart (vocals), Damian Rainauld (bass) and Ralph Alexander (drums). The group signed to
earMUSIC and released their debut album,
The Life I Remember, in September 2015. In August and September 2015, they toured the southern, midwestern and southwestern United States with
Fear Factory,
The Bloodline and
Before the Mourning. In 2016, Mader participated in music-production education through the
Nail the Mix platform, where he taught a mixing class based on
Gojira's song “Toxic Garbage Island.” In March 2019, it was announced that Mader (along with drummer
Chris Kontos) would perform with Machine Head for the first time in 21 years with a tour celebrating the 25th anniversary of the release of
Burn My Eyes; however, he and Kontos did not officially rejoin the band. == Discography ==
