Man Is The Bastard are really tight...
Havn't seen any d-beat here... Skitsystem, Wolfbrigade, the like? Blend of crust and death metal, with old school hardcore sensibilities. Oh yeah.
Someone earlier mentioned Black metal... how about Black-thrash punk? Agents of Satan. One bass, one vocalist, one drummer, much distortion. Fucking brutal.
Excruciating Terror rock as well, they are a grind band I recently discovered. I havn't really been listening to hardcore recently, and have basically dropped out of the scene to study and such (not that I was ever that involved, just went to shows and such, but still), so I'm always psyched when I find something new I like.
And yeah, its fucking blasphemy to say Limpwrist is better than Los Crudos
