Born in Montreal, Canada and raised in the suburb of Laval, QC, Denis knew at an early age that music and heavy metal were going to be part of his existence...fovever! When he used to scream "thrash till death" in the early 80's, he truly meant it. Growing up on a steady diet of Deep Purple, Black Sabbath, Led Zeppelin and Uriah Heep on the U.K. side and KISS, Ted Nugent, Aerosmith and Van Halen this side of the Atlantic, it was the perfect recipe to create a lifelong music enthousiast. In 1981, Denis purchased Venom "Welcome To Hell" and it changed his life musically and spiritually. Playing anything less intense was no longer an option and that's where the idea behind Aggression started...35+ years later..he is still doing it!!

Dave Watson began playing music at age 13 starting on bass and drums before moving to guitar at age 17 after hearing the song 'One Big Rush' by Joe Satriani.  Upon moving to Vancouver in 2006 he joined Entropia and recorded 3 albums with them and playing numerous shows on the Canadian west coast.  Following the disbanding of Entropia he joined Aggression in 2014.  His biggest influences on guitar include Joe Satriani, Dave Mustaine, Marty Friedman, Adrian Smith and Jani Liimatainen. Favorite bands include Iron Maiden, Megadeth, Children of Bodom, Testament and early Iced Earth. 

Kyle Hagen began playing bass the age of thirteen and has enjoyed a vast career in a number of bands having performed across Europe and North America. His musical influences span a variety of bands and bassists from the metal, jazz, classical and world music genres. Among his favourite bassists are Geezer Butler, Stanley Clarke and John Myung. Kyle is known in the Vancouver metal scene as the last bassist for Sinned, a death metal band who has contributed music to Year Of The Carnivore and shared the stage with Arch Enemy. He is also active with Assimilation (death-thrash), Opus Arise (symphonic metal), Roma-Jazz and a couple of tribute bands.

Born and raised in Surrey, British Columbia, Ryan Idris has always had an energy that could only be contained by playing the drums. Ryan has been playing drums, as well as guitar for nearly 15 years. Heavily rooted in the thrash metal genre, musical tastes were developing more towards technical and progressive ways. This sparked a craving of wanting to learn the instrument and music as a whole, more deeply. Having studied classical music and percussion at Douglas College for 2 years, he continued his remaining studies at Vancouver Community College where he learned more about jazz and drumset independance earning him a diploma in jazz and contemporary music at the age of 24. Over the past decade, Ryan has toured actively with  Aggression (2014-2018, 2020-present) and melodic thrash band Expain (2012-present) throughout Canada, the United States and Europe. He has shared the stage in support of many bands such as Revocation, Brujeria, Carcass, Sacrifice and Razor. Returning to Aggression after a 2 year hiatus, along with a new lineup, the excitement is higher than ever and the chemistry is brewing something evil.
