Jay was born in Jamaica, Illinois. Ken began playing drums early on and had played drums in a couple of metal bands early in his career in central Illinois before heading north to Chicago. Ken was the drummer in Deep Blue Dream, a band that also included Wayne Static and had auditioned at one point for Smashing Pumpkins but was told by Billy Corgan he was "too metal" to be in the band. He co-founded Static-X with Wayne Static in 1994. Ken played drums on the band's first two albums, Wisconsin Death Trip and Machine, but before Static-X could begin recording their third album, Shadow Zone, Jay left the band because of musical and political differences.
Shortly after his departure, he joined Godhead as a replacement drummer for a brief time. He has kept out of the media limelight since his departure.
In 2010, Ken stepped back into music to produce the debut album for Texas-based band, Blood Red Summer. He connected with the band through their guitar player, Erik Fincher, who had worked with Ken at a Virgin Records store in Los Angeles, CA, and later became Static-X's long time guitar tech.
