Logan Conrad Mader (born November 16, 1970) is a Canadian record producer and current guitarist of melodic death metal band Once Human, as well as the former lead guitarist of groove metal band Machine Head. Mader is most famous for his time in Machine Head, whose 1994 debut Burn My Eyes was released by Roadrunner Records and quickly became the top-selling debut album in the label's history until Slipknot's debut album. Their second album, The More Things Change..., was released in 1997 and Logan left the band shortly thereafter to divert his energy and time to side projects. Mader co-founded Dirty Icon Productions, a Los Angeles-based production team. They write, produce, record, mix, master, and engineer music for other artists. Biography Machine Head, Soulfly and Medication Machine Head formed on October 12, 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 (8 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. Stereo Black and production In June, 2003, Mader formed the band New Black, which was later renamed to Stereo Black. Although the band opened for Tesla and Hed PE, made a demo co-produced by Junkie XL, and created an Internet buzz, 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 in 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
