See Tommy, that is quite a nice list, except that it isn't really related to the OP at all and half of it is post-punk and new wave. Devo are punk only in the sense that Venom are a rock 'n roll band. I mean, partly I avoided post-punk and new wave because you start then getting into this ever broadening definition of punk and three posts down the line you're recommending the dude listen to Throbbing Gristle, early Bathory and All Aboute Eve.
I mean like, I tried to keep my suggestions fairly relevant. For example his liking of Stiff Little Fingers suggests 999 and The Undertones, whilst Leftover Crack suggests crust classics like Axegrinder and Amebix. Also you have that post in a file somewhere don't you?
