Gib786 - he asked for music with balls, not some emasculated gimp with a moustache whining about stuff.
For sheer brutality, buy the 'German' CD from Earache Records - It's Iron Monkey's two albums in one case. [Edit: Scratch that, just checked the webstore - they're only doing them seperately now; £8.57 each]
There has never been a band with the presence, power or sheer attitude of Iron Monkey.
Once you've listened to both albums many, many times, move on to Charger, early Pitch Shifter (give Brutal Cancroid or Gritter a spin), Carcass, Napalm Death (Circa Plague Rages/Breed To Breathe), Brujeria for a giggle, and finally The Berzerker and Agoraphobic Nosebleed just because they're simultaniously brilliantly heavy and terrible.
