Mikael's been giving a "musical nod" to a few of his big influences over the years. He's done Voivod-ish riffs here and there. The beginning riffs of Deliverance are a nod to Voivod as well. I have all their albums, and there's 3 phases of Voivod.
1-War and Pain, Rooooaaaarrr, and Killing Technology- very thrash/death oriented. Been around just as long as the "big 4"
2-Dimension Hatross, Nothingface, Angel Rat, Outer Limits- more prog injected. As IMTOD suggested, start with this era.
3-Negatron, Phobos, Voivod, and Katorz- first 2 with singer /bassist Eric Forrest...more stripped down, industrial in parts, but still proggish. The last 2 have Jason Newsted(longtime friend and fan) joining them. They're more straightfoward, streamlined metal albums.
I'd put them up there with Rush, and Devin Townsend (this is my opinion of course) as "THE" triarchy of Canada's best metal legends of all time.
