John Vanderslice (born May 22, 1967 in Gainesville, Florida) is an American musician, formerly of mk Ultra but now performing with his own band. After mk Ultra broke up in 1999, Vanderslice wasted little time building a solo reputation. In 2000, he gained national media attention over his single Bill Gates Must Die after concocting an elaborate hoax in which Microsoft supposedly threatened legal action over supposed trademark violations (the disc had a similar etching to a Windows installation disc).
