TOXIC REASONS - Ghost Town
You can't beat early 80's American hardcore... 
Yea, agree with that. Early straight edge bands; especially Teen Idles, Government Issue, State of Alert, Youth Brigade etc. and most of all Minor Threat

. + Minutemen, Septic Death and 7 Seconds. They kick ass!
But about UK bands I really appreciate also One By One, Generic and Helath Hazard. You know the group of bands where Sned used to play with? (Well Pleasent Valley Children too..) He also played with Oi Polloi couple of times as a spare drummer at tours in mids of nineties.
