D.R.I. (aka Dirty Rotten Imbeciles) were one of the first bands to fuse hardcore punk with thrash metal, along with Suicidal Tendencies and Corrosion of Conformity. Starting off as a speedy, straight-ahead punk band, they gradually mixed more elements of heavy metal into their sound; as they did so, their songs got longer and featured more sections and more variety in tempo. D.R.I. managed the then-rare feat of crossing over to metal audiences while retaining their skatepunk and hardcore fan bases -- they had something for all those audiences to love (or hate).
