Yup, the first album is great, for me a classic indeed!
Everything after that just didn’t satisfy me at all. As if they lost the anger or urgency…

Venice-style crossover, Suicidal Tendencies are from there too :)
No Mercy is linked to ST, so check them as well!

You’re gonna have fun. With some of them at least ;-)
