Thurston Moore reminisces about mix tapes (I like that he got the very idea of doing a 'mix-tape' from Robert Christgau.) This is kind of a touching essay, because it's not written by Thurston the musician - it's more about Thurston, the music fan.
Around 1980, there was a spontaneous scene of young bands recording singles of superfast hardcore punk - Minor Threat, Negative Approach, Necros, Battalion of Saints, Adolescents, Sin 34, the Meatmen, Urban Waste, Void, Crucifucks, Youth Brigade, the Mob, Gang Green. I was fanatical and bought them all as soon as they came out. I was just a dishwasher at a SoHo restaurant - not exactly raking in the dough - but I needed these sides!
