Vrenna was Billy Corgan's programmer for four months in 1997. While he was on tour with the Smashing Pumpkins, Vrenna got a call from Axl Rose, who invited Vrenna to spend time with Guns N' Roses. "I did for a couple weeks, but then decided I didn't want to join the band", said Vrenna.

Vrenna was chosen to take over the drumming responsibilities for Marilyn Manson after Ginger Fish was injured in 2004 during the Lest We Forget tour. He then replaced Madonna Wayne Gacy as the permanent keyboardist for Marilyn Manson. Vrenna co-produced the albums The High End of Low (2009) and Born Villain (2012). In April 2011, following the departure of Marilyn Manson's drummer Ginger Fish, Chris Vrenna was announced to be his official replacement. However, in November 2011, it was announced that Vrenna had parted ways with the band in order to focus on scoring movies and video games.

In 2015, Vrenna composed the music for the video game Call of Duty: Advanced Warfare Exo Zombies.
