Fancy yourself a hard-core fan? No, seriously. We mean hard-core as in die-hard -- and a fan of hardcore the music. Good. You're going to need to be to appreciate what this. Over at Artifacting.com, they've just posted 24 hours of hardcore, everything from Denver's Bum-Kon to MDC to the Vandals to Negative Approach to, well, about as many other bands as you think it would take to fill 24 hours of music. The occasion: a soundtrack to listen to while reading the second edition of American Hardcore: A Tribal History by Steven Blush. Tracks can be downloaded individually or in one giant (2.25 gig) zip file.
