Three Imaginary Boys by The Cure (1979)
The Cure are of course required listening for anyone even vaguely interested in '80s alternative. "10:15 Saturday Night", "Grinding Halt" and "Fire in Cairo" are the songs that most often end up on playlists (the latter being my favorite, I think). I'd say this first album slots into British post-punk, where later albums might better be called goth, shoegaze, or emo. I can even hear some '70s UK ska in "Accuracy." The Specials, Madness, and UB40 were all contemporaries of The Cure. Two Tone, I think it is or was called, which itself spurred the later American Ska Punk bands like The Mighty Mighty Bosstones, No Doubt, and Operation Ivy. You don't have to bother with the more granular subgenres, if you don't want to, but if you're one of those folks who likes to discover new music, it can be fun to leap head-first into the rabbit-hole. How else would you stumble over a band called Crispy Ambulance? But even if you don't want to go full-tilt music-nerd like I do, I still encourage anyone to look beyond the typical playlists, which often repeat the same few songs. Not just of The Cure, or of '80s alternative; all playlists of all genres, whatever your beat. After being bludgeoned senseless with "Go Your Own Way" and "Rhiannon" for literally decades, I think I was 35 years old when I heard "Tusk" for the first time.
Anyway, it was a while before I learned that
Boys Don't Cry (1980), The Cure's first North American release, was really a compilation album. It does have some songs you won't find on the band's first few studio albums, though. I think "Boys Don't Cry" itself was just a single for the British audience, which would have aggravated me. I was never into buying singles. So I guess I'm recommending
Three Imaginary Boys to the Americans and Canadians, and
Boys Don't Cry to the Brits. And if you're from somewhere else... uh... well... whichever. Or both.
