Pfeiffer began his music career in the mid 1980s, when, as a teen, he was a part of a thrash metal band called Beyond Death. The band's two other members went on to found the death metal band Cannibal Corpse in 1988. In 1994, Pfeiffer became a founding member and drummer of Goldfinger. He married Vicky Anderson, the band's Canadian publicist, in 1998. (Anderson left Universal Music in 1998. The couple divorced in 2011). In 2002, Pfeiffer moved from Los Angeles to his wife's hometown of Toronto where he eventually became a Canadian citizen. There, he started managing and producing punk bands. In 2005, Pfeiffer became an on-air host for 102.1 The Edge. Late in 2005, the Pfeiffers started their own record label, High 4 Records. Their first signing was Crush Luther whose self-titled CD was released on 13 February 2007. The next band to sign, Cauterize released the CD, Disguises, on 12 June 2007. He has also played with the Canadian Rock Band, "The Salads". Pfeiffer is a huge fan of ice hockey, mainly the NHL teams Buffalo Sabres and The Los Angeles Kings. Darrin was lucky to have witnessed the Kings win the 2014 Stanley Cup on home ice and states Wayne Gretzky would be the only man he would ever sleep with. Pfeiffer has performed an acoustic love song/tribute to a life-sized cardboard cut out of Wayne Gretzky midway through a Goldfinger set.
