Abel is from Kelowna, British Columbia and his childhood dream was to be a Paleontologist .  Since he was 2-years old, Abel has suffered from tinnitus due to a car accident, but he says "it's not that bad."  Growing up, he listened to Metal and Hip hop which he considers a strange combination.  He enjoyed the heavy rifts of the guitar and the tempo and flow of the instrumentals. Early in his career, Abel would promote shows and saw first-hand how the industry worked.  One of his earliest music influences were The Prodigy and dubstep pioneers Vex'd .  
In 2005, Abel dropped out his business program at the University of BC to pursue making music full-time. At first, his parents questioned his decision, but after witnessing him spend 12 hours a day learning how to produce tracks, they were reassured by his commitment to his craft.  Where Excision was based in Western Canada, there were virtually no other DJs around. The only two other DJs that were remotely close to him were Datsik and Downlink. 
On November 15, 2013, ReXcision unveiled a 250,000 watt sound system at the first Bank Center in Broomfield Colorado for the Boomfest event. The event included a quite special back-to-back set from Funtcase and Cookie Monsta along with Deltron 3030, Brillz, ill.Gates and Colorado locals Robotic Pirate Monkey. 
Starting in January 2014, Excision began a new tour covering North America with support from Dirtyphonics and Ill Gates. This new tour featured his "Executioner" video and light production. This time around, he brings a new 150,000 watt sound system from PK Sound.

2016 would be the debut tour of "The Paradox". The new production system made it's way across North America selling out countless venues with the support of Bear Grillz and Figure on most dates.
In 2017 Excision announced the inaugural year of his own dinosaur themed music festival, "Lost Lands". Lost Lands will take place at Legend Valley, Ohio September 29th through October 1st 2017. The lineup consists of many of the top bass music djs including: Excision, Datsik (musician) , Seven Lions , Zeds Dead , 12th Planet (musician) , Destroid , Kill the Noise , and many more. 
Excision believes that bass is meant to be felt more than heard and highly recommends people wear earplugs to his shows.  According to his Reddit AMA, Excision starts out his tracks in the following manner:
Placeholder drum loop then bass/melody, then change the drums to fit the bass/melody. Sometimes I make a whole intro before I even start the drop (Existence, X Rated, Raise Your Fist) You can usually tell which ones those are because of how epic and long the intro is. The main thing to remember is you are trying to tell a story with every song you make, make the most important part of your story first.
