Firstly "can't stand the Rezillos"by the Rezillos, just a super fun album. Somewhere between punk and new wave, lots of art school appreciation with the pure riot passion of punk. Also it's a solid slab of pop sensibility that makes it one of my all time favourite UK punk albums.
But my favourite punk album from the UK comes from these guys.
Machine gun etiquette by the Damned is just rammed full of great tracks and helped lay the foundations for the goth scene in the 80's.
They were always one of the more theatrical bands from the era and of the punk set had much better musicianship to back it all up. Tunes like this and smash it up helped prove that they weren't just another group of snotty kids who'd half seen a guitar before so could probably play it ok.
