Tech Death Day 2

So Technical Death Metal has to be one of my favourite genres of Metal but one thing annoys me, and that's when people say Progressive Metal and Technical Death Metal are interchangeable. Yes there are plenty of Tech Death bands that are Progressive but just because they are Technical does not mean they are progressive. For example Aeon are a Tech Death/Brutal Death Metal band and have very little if any Progressive elements in their music.

(This song has one of the most brutal screams in existence!)
