Punk/metal crossover pioneers D.R.I. (Dirty Rotten Imbeciles) performed at The Rock in Copenhagen, Denmark last night, blasting through a host of classics, including several from their 1987 album "Crossover,"  considered by many as one of the most important crossover thrash albums ever released.  The album was reissued last April, with remastered versions of the original 13 tracks plus 11 bonus tracks.  Footage from last night's performance can be viewed below.
