Zak Roberts from Denver, Colorado, United States has been recording and producing extreme electronic music since the mid-1990s. Under monikers such as AK-47 and DJ Rabies, Roberts produced a driving and abrasive hi-fi speedcore sound, pushing the envelope for DIY hardcore producers. Searching for a way to promote and support underground hardcore music, Roberts co-founded the now infamous trashcore label Dtrash Records with fellow digital hardcore comrades CPUWar.
