Avoid Phallus dei cos i'll be honest apart from the first track it is pretty shit. Tanz Der Lemming is pretty impenetrable for a beginner. Later stuff like Hijack avoid at all costs, but if you come across a cheap 'Made In Germany' get that as it's got the great 'Loosey girls' which is worth the admission.
The best album is Paradieswarts duul by AD 1, just for the bonus tracks which pre-empt Sousxie and the Banshees circa Join Hands by 8 years
