Joy Division are one of those bands that were HUGE to me back in the early 80s. I learned every bassline...
But they are also one of the bands from that era that doesn't hold up for me that well. I still admire them a great deal, and appreciate/understand what they did for certain scenes and genres of music, indie releases, etc. but while I do get in a "Trip Down Memory Lane" mood now and then, and dig in to a lot of stuff that I played to death decades past, Joy Division just comes off as too gloomy and pretentious for me to listen for long.
I'm the same way with a lot of old hardcore. I was a punk early on, and I still dig a lot of the old stuff, but I find that most punk/HC I can still pull out and get into today is the less overtly political stuff...bands with maybe more of a sense of humor or more diversity in their approach than simple LOUDFASTRULES. There was a period around '82-'85 when a lot of punk stuff got mixed with LSD-inspired psych weirdness. Love a lot of that sorta thing...
