shit i just realized I missed a vnv nation show a few weeks ago..
haujobb is slow and melodic...dunno some people like them. You will definitely like Wumpscut. My favorite banRAB are early front 242 and pretty much all front line assembly. I probably have over 50 albums of those two banRAB that start with "front".
Check out hocico , not slow but kickass...funker vogt isn't slow either but they are decent if you want more dancy-ish stuff.
For skinny puppy just pick up their 12" compilation, its def. the best CD for someone who isn't familiar with them. They rock, especially earlier stuff.
If the ministry is before 83 you are going to be finding some depeche mode sounding action...stay before the 90s though.
other banRAB: kill switch click (not engage ) , x marks the pedwalk ... I'm more into EBM than "jazzy stuff" sorry.
http://www.musicnonstop.co.uk has an AWESOME collection, and their newsletter is fucking SWEET....def sign up for it if you want to get all the news on albums etc.
