I wouldn't say early Metallica is slower paced than early Megadeth. Look at Dyer's Eve, Battery, Fight Fire with Fire, Whiplash, to name one from each of their first 4.
A song or two from each album doesnt change the fact that early Metallica was not as fast or as speedy as Megadeth, and honestly that cant even be argued.
Testament? The New Order.
Indeed, you could have included
The Gathering ** I meant
The Legacy, i always mix those two up ** also, but cmon now man, they are basically considered to be the kings of mid-paced thrash, no other albums define that sound better than
PWYP,
TNO,
SoB and
The Ritual.
Since when is Overkill slow?
I never said they're slow, none of the bands mentioned on this topic are. But yes are definitely a mid-paced thrash metal band, and none of their albums are as fast and aggressive as
KIMB. Most of their albums are littered with mid-paced tracks.
And yeah, i dont really know why i threw Metal Church in there, as i dont consider them to be a thrash band either ... but their first two are pretty heavy on thrash.
BBB the album is thrashy. BBB the band is great live. To be honest I can't listen to their albums though.
I cant stand the band, and i already mentioned how i feel about the album.
Good example from the 80's would be Vio-Lence - Eternal Nightmare for full on thrash.

One of my all time favorites right there.
