Machine Head formed on October 12th 1991 with Mader on lead guitar, Robb Flynn on guitar and vocals, Adam Duce on bass and Tony Costanza on drums. He played with Machine Head through two albums until early 1998. After Logan's six year run with Machine Head, he joined the band Soulfly where he filled the slot as guitarist for their 1998 world tour. Logan'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, Logan left Soulfly in January 1999.
Shortly after the dissolution of Medication, Logan formed the band New Black, which was later changed to Stereo Black. Although the band opened for a local Hed PE gig, tracked a full demo, shopped it to a few labels and created an internet buzz, they were never signed. Years later, the Stereo Black track Save Me which was later called Inside. The song was featured in the trailer for Max Payne and The Butterfly Effect 2 and in the direct to video film Never Back Down 2: The Beatdown. They also created a song for the Scream 4 soundtrack, titled "Denial."
Currently, Logan runs Dirty Icon Productions, a Los Angeles based production team, alongside partner, Lucas Banker. Dirty Icon, published by Reverb/Universal, writes, produces, records, mixes and masters for other artists.
