I reckon I'll forever remain totally devoted to top-flight thrash and death metal----both of which are the brands of extreme metal music that I've always admired and loved the most. And I listen to thrash and DM records daily. I never could tolerate most of glam/hair metal and power metal bands. And although I've encountered tons of Black Metal fans everywhere from message forum boards to upfront in real life, I confess to being mostly a non-fan of BM. Top-tier Death Metal music and bands float my own boat by way more than BM ever did.
I've got loads of favourite bands in Thrash and DM, so lemme just name some of the leading lights and MVPs in my gallery of personal all-time favourites:
Thrash: (in random order)
Slayer
Anthrax
Megadeth
Dark Angel
Testament
Vio-lence
Exodus
Kreator
Sanctuary
....there are more, but I'll just stop here..
Death Metal:
Suffocation
Immolation
Cryptopsy
Incantation
Malevolent Creation
Morbid Angel
Death
Obituary
Atheist
Vader
Dying Fetus
Morpheus Descends
Again, I gotta stop cos there are obviously many more.
In DM, I've always been a far greater fan of the American scene than I've ever been of the European (i.e, the predominantly Swedish style and sound). Florida and NYDM are what I have forever loved and enjoyed most. I basically don't like progressive/melodic metal much at all. The Swedish style just doesn't thrill me much and actually bores me quite a bit. Besides, in DM, I realize how over the last few years, I've even strongly gravitated toward the Brutal/Tech death style which gives me a tremendous buzz. To cite as evidence; Suffocation have long been one of my greatest DM heroes. I'd recommend any newbie extreme metal fan to discover and sample for themselves albums by any of the bands I've mentioned above. They all play some of the greatest music my ears have heard so far.
