They’re one of my favourite ever bands. It’s hard to know where to suggest start because they are wildly varied and experimental. You could go with their dramatic, cold wave electro pop phase (one of my favourite songs of all time):
Or them in full 80s pop mode (the big hit):
Or in ultra torch lounge mode (this is from Perhaps):
Sulk is generally considered their best album (it has the hits on). I can’t really choose between that and the earlier The Affectionate Punch or the compilation of a sequence of eps they released in 1981 (Fourth Drawer Down) which are both uneven but thrillingly ambitious. Perhaps is more of an outlier - derided by critics at the time but due a re-appraisal
