I saw them open for System of a Down on the S.C.I.E.N.C.E. Tour and they were incredible. That was the 1st time I ever saw a drummer play sideways I remember.
I know they played:
Certain Shade of Green
You will be a hot dancer
Take me to your leader
and maybe 1 more off Fungus Amongus or Nebula
That's about as obscure Thrash/funk as they ever were. hahaha
