that's a perfect description
Classic Crossover\Thrash lives on!
More Crossover. It's basically Thrash mixed with Hardcore Punk. Evolved in the 80s. Started with DRI and Suicidal Tendencies, even Anthrax uses a bit of it. Slam riffs and quick solos, and a spitfire vocal delivery is what makes up Crossover. Also a heavy dose of audible bass guitar and lightning quick drum fills and tons of snare.
Going back all the way to...1983
The above album was more of a straight Hardcore Punk LP. This one is more in line with what Crossover Thrash sounds like. Came out in 88 (I was 1 years old XD)
The other band that helped to stabilize Crossover. This one came out in 83
By the way, the song Institutionalized was used in the first Iron Man movie during one of Tony's workshop scenes.
