They have interesting stuff to find out there... I should relisten... been a while...
Here was the 2013 second album comeback after 30 years... I've been enjoying it like heck recently. It's well done and has interesting production, weird violin and funk bass in with the thrashy punk.

This collection of early stuff starts pretty trad punk and gets weird, bauhaus -esque. Werewolf is a spooky 10 minute ride.
Playlist of first album, For Madmen Only. I quick browsed to remember why it caught my ear long ago and it's the jaggy post-punk sound.
There's some Peel Sessions that might be worth seeking. That's on this odds & demos comp I'd never heard of until now. Interesting.
Funny, they also did uncharacteristic, upbeat punk with a football team for charity.
