Starter Kit: Thrashcore/Crossover Thrash

My last Starter Kit (on Contemporary Thrash) brought in more recent bands and albums that cranked their amps past 11 and shredded faces with their speed. However, any genre is (to quote Shrek), like an onion; there are layers and layers of difference all balled up in one, and thrash metal is no different. While most people are at least aware of the genre’s staples (Metallica, Slayer, Anthrax, Megadeth, etc.), they might not know of the lesser known bands that speed even past the big names.
