Give this song a listen. Devin Townsend is one hell of a musician. Has one of the most powerful voices in music, a truly extraordinary guitarist and writes some of the best metal I've ever heard.
You might have heard of Death if not then you have now. Chuck Schuldiner who formed Death is considered the godfather of Death Metal and the man who most people agree ended up creating the genre of Death Metal. Chuck was one of the most technically skilled guitarists on this planet and his songwriting skills were a notch above almost everyone in Death Metal and even Metal in general. His vocal work is good too and you can understand what he is saying. Another thing Chuck doesn't just write about gore and dying like a lot of Death Metal bands do, I'm talking to you Cannibal Corpse he wrote about a lot of political, social and philosophical topics. When the band first released their debut album Scream Bloody Gore in 1987 that style of music was unheard of. I mean sure you had Slayer, Possessed, Venom and a few other bands release material already that was pretty damn fast and heavy but nothing like what Death sounded like
The first song Infernal Death from their debut from 1987
The last original song from their final album The Sound Of Perseverance from 1998
You can clearly see the major progression in their playing style. Also Chuck's vocals also changed a bit. Sadly the greatest guitarist in my opinion died on December 13, 2001 of brain cancer. One of the biggest losses in metal by far.
