All those American thrash bands have essentially the same trajectory: '80-'83 demos/creation of local following, '83-'90 classic after classic, '90-'92 peak commercial success, '93-'03 creativity bottoms out and/or desperate attempt to change your sound due to a shifting metal/hard rock landscape that isn't interested in you anymore, '03- you have now achieved legend status due to a nostalgic fanbase, the internet, and a healthy international audience; capitalize by touring across the globe. This pretty much goes for all mainstream metal that weren't involved in an extreme underground scene or those that didn't initially resonate with the metal audience.
