My favorite band is Depeche Mode. Most Americans know about them. My second favorite of all time is Heaven 17. They didn't get that big here in the US, even though they deserved to. Here's my favorite song of theirs, Temptation.
They did some really cool political music too. For instance, (We Don't Need This) Fascist Groove Thang
And, there's always, Let's All Make a Bomb
I'll leave you with Crushed by the Wheels of Industry.
